Stabilization of poly-L-lysine/DNA polyplexes for in vivo gene delivery to the liver. (1/6763)

We are developing a self-assembling non-viral in vivo gene delivery vehicle based on poly-l-lysine and plasmid DNA. We have characterized poly-l-lysines of different chain lengths for DNA condensation and strength of DNA binding. Poly-l-lysine chains >20 residues bound DNA efficiently in physiological saline, while shorter chains did not. Attachment of asialoorosomucoid to PLL increased the PLL chain length required for efficient DNA binding in saline and for efficient DNA condensation. By electron microscopy, poly-l-lysine/DNA polyplexes appeared as toroids 25-50 nm in diameter or rods 40-80 nm long; conjugation of asialoorosomucoid to the polylysine component increased the size of resulting polyplexes to 50-90 nm. In water, poly-l-lysine and asialoorosomucoid-PLL polyplexes have effective diameters of 46 and 87.6 nm, respectively. Polyplexes containing only poly-l-lysine and DNA aggregated in physiological saline at all charge ratios and aggregated at neutral charge ratios in water. Attachment of asialoorosomucoid lessened, but did not eliminate, the aggregation of PLL polyplexes, and did not result in efficient delivery of polyplexes to hepatocytes. Conjugation of polyethylene glycol to poly-l-lysine sterically stabilized resulting polyplexes at neutral charge ratios by shielding the surfaces. For efficient in vivo gene delivery, polyplexes will need to be sterically stabilized to prevent aggregation and interaction with serum components.  (+info)

Partial purification and properties of porcine thymus lactosylceramide beta-galactosidase. (2/6763)

Porcine thymus lactosylceramide beta-galactosidase was purified by a simple procedure. In the final step of isoelectric focusing the enzyme was separated into two peaks of pI 6.3 (peak I) and 7.0 (peak II), which showed 3,600- and 4,000-fold enhancement of lactosylceramide-hydrolysing activity, respectively. The two peaks had identical mobility on polyacrylamide gel electrophoresis. The apparent molecular weight was 34,000. Neither monosialoganglioside (GM1) nor galactosylceramide was hydrolysed by the purified enzyme fractions. The optimal pH was at 4.6, and sodium taurocholate was essential for the reaction. The apparent Km was 2.3 x 10-5 M. The reaction was stimulated by sodium chloride and linoleic acid, while it was strongly inhibited by Triton X-100 and bovine serum albumin.

Lipase [EC 3.1.1.3] depleted lipid micelles, in which lipolysis was not elicited by adrenaline, were prepared from lipid micelles. When these lipase-depleted lipid micelles incubated with adipose tissue extract containing lipase activity, adrenaline-induced lipolysis was restored to almost the same level as that of native lipid micelles. Adrenaline-induced lipolysis was not restored when the lipase-depleted lipid micelles were homogenized or sonicated. Various tissue extracts from kidney, lung, liver, and pancreas, and post-heparin plasma, which contained lipase activity, restored adrenaline-induced lipolysis in lipase-depleted lipid micelles.  (+info)

A lipid modified ubiquitin is packaged into particles of several enveloped viruses. (4/6763)

An anti-ubiquitin cross-reactive protein which migrates more slowly (6.5 kDa) by SDS-PAGE than ubiquitin was identified in African swine fever virus particles. This protein was extracted into the detergent phase in Triton X-114 phase separations, showing that it is hydrophobic, and was radiolabelled with both [3H]palmitic acid and [32P]orthophosphate. This indicates that the protein has a similar structure to the membrane associated phosphatidyl ubiquitin described in baculovirus particles. A similar molecule was found in vaccinia virus and herpes simplex virus particles, suggesting that it may be a component of uninfected cell membranes, which is incorporated into membrane layers in virions during morphogenesis.  (+info)

Structural and functional consequences of antigenic modulation of red blood cells with methoxypoly(ethylene glycol). (5/6763)

We previously showed that the covalent modification of the red blood cell (RBC) surface with methoxypoly(ethylene glycol) [mPEG; MW approximately 5 kD] could significantly attenuate the immunologic recognition of surface antigens. However, to make these antigenically silent RBC a clinically viable option, the mPEG-modified RBC must maintain normal cellular structure and functions. To this end, mPEG-derivatization was found to have no significant detrimental effects on RBC structure or function at concentrations that effectively blocked antigenic recognition of a variety of RBC antigens. Importantly, RBC lysis, morphology, and hemoglobin oxidation state were unaffected by mPEG-modification. Furthermore, as shown by functional studies of Band 3, a major site of modification, PEG-binding does not affect protein function, as evidenced by normal SO4- flux. Similarly, Na+ and K+ homeostasis were unaffected. The functional aspects of the mPEG-modified RBC were also maintained, as evidenced by normal oxygen binding and cellular deformability. Perhaps most importantly, mPEG-derivatized mouse RBC showed normal in vivo survival ( approximately 50 days) with no sensitization after repeated transfusions. These data further support the hypothesis that the covalent attachment of nonimmunogenic materials (eg, mPEG) to intact RBC may have significant application in transfusion medicine, especially for the chronically transfused and/or allosensitized patient.  (+info)

Enhancement of endocytosis due to aminophospholipid transport across the plasma membrane of living cells. (6/6763)

Formation of intracellular vesicles is initiated by membrane budding. Here we test the hypothesis that the plasma membrane surface area asymmetry could be a driving force for vesicle formation during endocytosis. The inner layer phospholipid number was therefore increased by adding exogenous aminophospholipids to living cells, which were then translocated from the outer to the inner layer of the membrane by the ubiquitous flippase. Addition of either phosphatidylserine or phosphatidylethanolamine led to an enhancement of endocytosis, showing that the observed acceleration does not depend on the lipid polar head group. Conversely, a closely related aminophospholipid that is not recognized by the flippase, lyso-alpha-phosphatidylserine, inhibited endocytosis, and similar results were obtained with a cholesterol derivative that also remains in the plasma membrane outer layer. Thus an increase of lipid concentration in the inner layer enhanced internalization, whereas an increase of the lipid concentration in the outer layer inhibited internalization. These experiments suggest that transient asymmetries in lipid concentration might contribute to the formation of endocytic vesicles.  (+info)

The pharmacokinetics of artemisinin after administration of two different suppositories to healthy Vietnamese subjects. (7/6763)

Eight healthy Vietnamese male subjects received 400 mg artemisinin formulated into fatty suppositories (FS), and six different subjects received 500 mg of artemisinin formulated in polyethylene glycol suppositories (PEGS). Plasma concentrations were measured by high-performance liquid chromatography with electrochemical detection; concentration versus time curves were analyzed with nonparametric methods. No statistically significant differences were found between the two formulations. The maximum concentration (Cmax) was 100 +/- 102 microg/L (mean +/- SD, range = 24-330) microg/L (FS), the pharmacokinetic lag time (Tlag) was 1.3 +/- 1.0 hr (range = 0-3) (FS), and the time of the maximum concentration (Tmax) was 7.1 +/- 2.1 hr (range = 3-10) hr (FS). Because artemisinin is not available for intravenous dosage, absolute bioavailability cannot be assessed. However, compared with a previous study on oral artemisinin in healthy Vietnamese subjects, bioavailability relative to oral administration was estimated to be approximately 30%. We conclude that therapeutic blood concentrations of artemisinin can be reached after rectal dosage. The dose after rectal administration should probably be higher than after oral administration; doubling or tripling the oral dose might be necessary, which would imply a rectal dose of at least 20 mg/kg of body weight given twice a day.  (+info)

Opposite behavior of two isozymes when refolding in the presence of non-ionic detergents. (8/6763)

GroEL has a greater affinity for the mitochondrial isozyme (mAAT) of aspartate aminotransferase than for its cytosolic counterpart (cAAT) (Mattingly JR Jr, Iriarte A, Martinez-Carrion M, 1995, J Biol Chem 270:1138-1148), two proteins that share a high degree of sequence similarity and an almost identical spatial structure. The effect of detergents on the refolding of these large, dimeric isozymes parallels this difference in behavior. The presence of non-ionic detergents such as Triton X-100 or lubrol at concentrations above their critical micelle concentration (CMC) interferes with reactivation of mAAT unfolded in guanidinium chloride but increases the yield of cAAT refolding at low temperatures. The inhibitory effect of detergents on the reactivation of mAAT decreases progressively as the addition of detergents is delayed after starting the refolding reaction. The rate of disappearance of the species with affinity for binding detergents coincides with the slowest of the two rate-limiting steps detected in the refolding pathway of mAAT. Limited proteolysis studies indicate that the overall structure of the detergent-bound mAAT resembles that of the protein in a complex with GroEL. The mAAT folding intermediates trapped in the presence of detergents can resume reactivation either upon dilution of the detergent below its CMC or by adding beta-cyclodextrin. Thus, isolation of otherwise transient productive folding intermediates for further characterization is possible through the use of detergents.  (+info)

We have explored the concept of using the bacterial enzyme thiaminase to disrupt energy metabolism in cancer. To optimize the biological and pharmacologic properties of this enzyme, we studied the effects of modifying it with the addition of linear polyethylene glycol chains of various sizes, a common technique that can increase plasma retention time and reduce immunogenicity of foreign proteins. Figure 1 demonstrates that the protein was successfully modified by these PEG chains of various lengths. For most of the subsequent studies we focused on the intermediate, 5k-PEG modified thiaminase enzyme in comparison with native enzyme.. We initially hypothesized that thiaminase worked through an extracellular mechanism of action, by catabolizing extracellular thiamine and causing acute thiamine starvation. Indeed, Fig. 2 shows that both native and 5k-PEG thiaminase are very potent in the catabolism of thiamine, achieving a 100-fold reduction of thiamine in medium at concentrations of 0.0001 ...

Press Release issued Dec 8, 2016: Polyethylene glycol (PEG) is one of the most frequently used non-ionic polymers in polymer-based drug delivery and other bioactivities. Since polyethylene glycol has high aqueous solubility, it is considered for pro-drug conjugation. This appreciative status and use of PEGlycation technology in biotechnological and pharmaceutical applications has led to many progressive steps in the medical field. The existent scientific literature testifies for the various applications of polymers derived from polyethylene glycol (PEGs). The collective experience surrounding this material and relief provided by governing authorities around the world regarding its usage will lead to its increased usage in many medical device applications and drugs, which in turn will expand the market for polyethylene glycol in research and development areas. Better opportunities are predicted for the polyethylene glycol market in a range of applications such as diagnostics areas and drug development,

Sustained Virological Response to Pegylated Interferon Alfa-2b (PegIntron) with or without Ribavirin Predicts Continued Response through 5 Years Sustained virological response (SVR), or continued undetectable HCV viral load 24 weeks after completion of interferon-based therapy, is widely regarded as a cure for chronic hepatitis C.. As reported at the recent Digestive Disease Week 2008 conference in San Diego, Karen Lindsay and an international team of colleagues conducted a study to confirm whether SVR predicts long-term (, 5 years) HCV clearance in adults treated with pegylated interferon, as has already been demonstrated for conventional interferon.. The present analysis included 567 adult chronic hepatitis C patients from 2 previously published clinical trials (Lindsay et al, Hepatology 2001, 34:395-403; Manns et al, Lancet 2001, 358:958-965) who were treated with pegylated interferon alfa-2b (PegIntron) with or without ribavirin..

Cooksley et al 2003 is an open-label trial, which assessed the efficacy and safety of different doses of peginterferon alfa-2a vs. interferon alfa-2a 4.5 MIU for 24 weeks of therapy followed by 24 weeks of treatment-free follow up in 194 interferon-naïve patients with chronic hepatitis B. There was a non-significant higher incidence of serious adverse events in the peginterferon alfa-2a 180μg/week group (8.6%) as compared with interferon 4.5 MIU /three times a week group (4%). The most common causes of SAEs were gastrointestinal disorders and infections. There was no difference in virologic or immunologic outcomes (such as loss of DNA or seroconversion) between peginterferon alfa-2a 180μg/wk and interferon alfa-2a 4.5 MIU group. The basis of choosing 180μg/week dose as the recommended dose is not clear since the efficacy in terms of surrogate outcome measures did not differ among the different peginterferon regimens (90, 180 and 270μg/week) and the number of patients who required dose ...

As not all patients achieve a sustained response with the standard duration of interferon-based therapy, a current focus of research is to identify ways of increasing the post-treatment response rate to peginterferon alfa-2a. Early studies have shown that additional benefits can be obtained by HBeAg-negative patients when the duration of conventional interferon therapy is extended beyond 1 year.6,7 A pilot study highlighted that the advantages of extension therapy initially observed with conventional interferon were also apparent following treatment with peginterferon alfa-2a.8 It is possible that the pattern of HBsAg decline during treatment may help identify patients for whom extended therapy should be ...

1.Previous studies have indicated that the permeability of polyethyleneglycol across the human intestine is anomalously high in comparison with the permeability of sugars with similar molecular mass. In consequence it has been proposed that two or more distinct mechanisms must exist for the translocation of these classes of molecule or, alternatively, that the molecular parameter determining rate of penetration is each molecules minimum molecular dimension.. 2.The notional hydrogen-bonding capacity of a molecule correlates well with oil-water partition coefficient and also, in a variety of experimental systems, with rate of passive diffusion across biological membranes. A molecules hydrogen-bonding capacity is calculated by inspecting the structural formula and summing the individual theory-derived hydrogen-bonding capacities of the molecules functional groups.. 3.A classic set of intestinal permeability data that includes several ethyleneglycol oligomers and several sugars is re-analysed.

Protein PEGylation (covalent attachment of poly(ethylene glycol) or PEG to proteins) is an excellent example of a drug delivery system that improves pharmacokinetics and pharmacodynamic properties of therapeutics. However, although PEGylation is clinically proven and attracts both scientific and commercial interest, the technique is associated with many process constraints, in particular related to controlling the number of conjugated PEG chains. A novel, solid-phase PEGylation methodology was attempted to overcome the drawbacks of the commonly used solution-phase methods for preparing PEGylated products. The solid-phase PEGylation methodology involved conjugating protein onto a tethered PEG derivative attached onto a solid matrix, followed by hydrolytic cleavage of the PEG chain from the solid matrix under mild conditions to yield PEGylated protein in free solution. PEGs with molecular weights (MWs) 2000 and 4000 Da were used and a heterobifunctional PEG derivative, α-(β-alanine)-ω-carboxy ...

The purpose of this study is to determine if 24 weeks of treatment with Pegylated Interferon Lambda plus Ribavirin and 12 weeks of treatment with Pegylated Interferon Lambda plus Ribavirin and Daclatasvir will be safe and effective for treatment of hepatitis C compared to 24 weeks of treatment with Pegylated Interferon Alfa-2a plus Ribavirin.. ...
A combination of weekly pegylated interferon (peginterferon) alpha and daily ribavirin represents the standard of care for the treatment of chronic hepatitis C according to current guidelines. It is not established which of the two licensed products (peginterferon alpha-2a or peginterferon alfa-2b) is most effective. We performed a systematic review of head-to-head randomized trials to assess the benefits and harms of the two treatments. We searched the Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, and LILACS through July 2009. Using standardized forms, two reviewers independently extracted data from each eligible trial report. We statistically combined data using a random effects meta-analysis according to the intention-to-treat principle. We identified 12 randomized clinical trials, including 5,008 patients, that compared peginterferon alpha-2a plus ribavirin versus peginterferon alfa-2b plus ribavirin. Overall, peginterferon alpha-2a significantly increased the number of ...

Although HCV-monoinfected patients with an HCV genotype of 1 can expect a 40-45% chance of an SVR using pegylated interferon/ribavirin, HIV/HCV-coinfected patients with genotype-1 are looking at an SVR of 14% (ACTG) to 29% (Apricot). The results in co-infected patients with genotypes 2/3 infections were encouraging with 45% (Ribavic) to 62% (Apricot) SVRs. However, it is important to note that all patients received 48 weeks of therapy. It is likely that, in order to achieve an optimal response, all genotype 2/3 HIV/HCV co-infected patients should receive 48 weeks of treatment with pegylated interferon/ribavirin.. HCV-RNA was associated with treatment outcome in Apricot, but not Ribavic. Analysis, especially for patients with genotype -1 co-infections, by baseline viral loads were not available. It is likely that those with high HCV viral loads (800,000 iu/l) will have poor responses. Although, baseline CD4 counts have been shown to affect response to therapy, patients in both Ribavic and Apricot ...

BACKGROUND: Any benefit of adjuvant interferon alfa-2b for melanoma could depend on dose and duration of treatment. Our aim was to determine whether pegylated interferon alfa-2b can facilitate prolonged exposure while maintaining tolerability. METHODS: 1256 patients with resected stage III melanoma were randomly assigned to observation (n=629) or pegylated interferon alfa-2b (n=627) 6 mug/kg per week for 8 weeks (induction) then 3 mug/kg per week (maintenance) for an intended duration of 5 years. Randomisation was stratified for microscopic (N1) versus macroscopic (N2) nodal involvement, number of positive nodes, ulceration and tumour thickness, sex, and centre. Randomisation was done with a minimisation technique. The primary endpoint was recurrence-free survival. Analyses were done by intention to treat. This study is registered with ClinicalTrials.gov, number NCT00006249. FINDINGS: All randomised patients were included in the primary efficacy analysis. 608 patients in the interferon group and ...
BACKGROUND Data are limited on the efficacy and safety of pegylated interferon plus ribavirin for patients with hepatitis C virus genotype 1 (HCV-1) receiving hemodialysis. OBJECTIVE To compare the efficacy and safety of combination therapy with pegylated interferon plus low-dose ribavirin and pegylated interferon monotherapy for treatment-naive patients with HCV-1 receiving hemodialysis. DESIGN Open-label, randomized, controlled trial. (ClinicalTrials.gov: NCT00491244). SETTING 8 centers in Taiwan. PATIENTS 205 treatment-naive patients with HCV-1 receiving hemodialysis. INTERVENTION 48 weeks of pegylated interferon-α2a, 135 µg weekly, plus ribavirin, 200 mg daily (n = 103), or pegylated interferon-α2a, 135 µg weekly (n = 102). MEASUREMENTS Sustained virologic response rate and adverse event-related withdrawal rate. RESULTS Compared with monotherapy, combination therapy had a greater sustained virologic response rate (64% vs. 33%; relative risk, 1.92 [95% CI, 1.41 to 2.62]; P | 0.001).

Antibodies against polyethylene glycol (PEG) in healthy subjects raise concerns about the efficacy of pegylated drugs. We evaluated the prevalence of antibodies against PEG among patients with acute lymphoblastic leukemia (ALL) prior to and/or immediately after their first dose of pegylated E.coli asparaginase (PEG-ASNase). Serum samples of 701 children, 673 with primary ALL, 28 with relapsed ALL, and 188 adults with primary ALL were analyzed for anti-PEG IgG and IgM. Measurements in 58 healthy infants served as reference to define cut-points for antibody-positive and -negative samples. Anti-PEG antibodies were detected in ALL patients prior the first PEG-ASNase with a prevalence of 13.9% (anti-PEG IgG) and 29.1% (anti-PEG IgM). After administration of PEG-ASNase the prevalence of anti-PEG antibodies decreased to 4.2% for anti-PEG IgG and to 4.5% for anti-PEG IgM. Pre-existing anti-PEG antibodies did not inhibit PEG-ASNase activity but significantly reduced PEGASNase activity levels in a ...

Glycol: any of a class of organic chemicals characterized by having separate two hydroxyl (-OH) groups, contribute to high water solubility, hygroscopicity and reactivity with many organic compounds, on usually linear and aliphatic carbon chain. The general formula is CnH2n(OH)2 or (CH2)n(OH)2. The wider meaning names include diols, dihydric alcohols, and dihydroxy alcohols. Polyethylene glycols and polypropylene glycols are sometimes called polyglycols which are derived by polymerization of ethylene oxide and propylene oxide respectively. Polyethylene glycols are water-soluble at all molecular weights, but polypropylene glycols become increasingly less water-soluble at high molecular weights. Ethylene glycol, HOCH2CH2OH, is the simplest member of the glycol family. Mono-, di- and triethylene glycols are the first three members of a homologous series of dihydroxy alcohols. They are colourless, essentially odourless stable liquids with low viscosities and high boiling points. Ethylene glycol is a ...

BARCELONA, Spain, Apr 19, 2012 (BUSINESS WIRE) --Gilead Sciences, Inc. (Nasdaq:GILD) today announced interim data from a Phase 2 trial (ATOMIC) examining a 12-week course of treatment with the once-daily nucleotide GS-7977 plus pegylated interferon (Peg-IFN) and ribavirin (RBV) in treatment-naïve patients with genotype 1 chronic hepatitis C virus (HCV) infection. The study found that 90 percent of patients (n=47/52, missing data equals failure analysis) achieved a 12-week sustained virologic response (SVR12), defined as maintaining undetectable viral load (HCV RNA ,25 IU/mL) 12 weeks after the completion of therapy. These findings will be presented today during an oral session at the 47th Annual Meeting of the European Association for the Study of the Liver (International Liver Congress 2012) in Barcelona, Spain. These data suggest that this GS-7977-based regimen could offer most patients with genotype 1 a simple, short, three-month course of treatment with very high cure rates, said Kris ...
Three PEG molecules (PEG-methacrylate, -diacrylate and -dimethacrylate) were incorporated into galactose-based polyacrylate hydrogels and their relative abilities to reduce non-specific protein adsorption in immunoassays were determined. Highly crosslinked hydrogels containing amine-terminated functionalities were formed and used to covalently attach antibodies specific for staphylococcal enterotoxin B (SEB). Patterned arrays of immobilized antibodies in the PEG-modified hydrogels were created with a PDMS template containing micro-channels for use in sandwich immunoassays to detect SEB. Different concentrations of the toxin were applied to the hydrogel arrays, followed with a Cy3-labeled tracer antibody specific for the two toxins. Fluorescence laser scanning confocal microscopy of the tracer molecules provided both qualitative and quantitative measurements on the detection sensitivity and the reduction in non-specific binding as a result of PEG incorporation. Results showed the PEG-modified hydrogel
Comparison of pegylated interferon monotherapy and de novo pegylated interferon plus tenofovir combination therapy in patients with chronic hepatitis B
Under-enrolment of women to randomized clinical trials, including chronic hepatitis C, has long been recognized. The aim of this study was to identify factors predictive of sustained virological response (SVR) to PEG IFN/Ribavirin antiviral therapy in relation to gender and reproductive status of female patients involved. Seven hundred and forty-six treatment-naïve patients (431 men, 315 women) treated with Peg-IFNα-2a (180 μg/week) or Peg-IFNα-2b (1.5 μg/kg/week) plus ribavirin (800-1400 mg/day) for 24 or 48 weeks were studied between 2006 and 2010. Differences in SVR rate, overall and by gender were assessed after adjustment and propensity score matching. SVR was obtained in 44.2% of Peg-IFNα-2a-treated patients and in 51.2% of Peg-IFNα-2b-treated patients (intention-to-treat; P = 0.139). Age, fibrosis stage and genotype 2 and 3 were independently associated with SVR by multivariate analysis. Analysing by gender, the difference in SVR between PEG-IFNα types was not significant in men ...

AU - Whyte, Andrew. AU - Huang, Jining. AU - Pollit, Lori. AU - Farokhzad, Omid C.. PY - 2015/8/1. Y1 - 2015/8/1. N2 - The remarkably high intracellular concentration of reducing agents is an excellent endogenous stimulus for designing nanocarriers programmed for intracellular delivery of therapeutic agents. However, despite their excellent biodegradability profiles, aliphatic polyesters that are fully degradable in response to the intracellular reducing environment are rare. Herein, a reduction-responsive drug delivery nanocarrier derived from a linear polyester bearing disulfide bonds is reported. The reduction-responsive polyester is synthesized via a convenient polycondensation process. After conjugation of terminal carboxylic acid groups of polyester to polyethylene glycol (PEG), the resulting polymer ...
The incorporation of poly(ethylene glycol) (PEG)-conjugated lipids in lipid-based carriers substantially prolongs the circulation lifetime of liposomes. However, the mechanism(s) by which PEG-lipids achieve this have not been fully elucidated. It is believed that PEG-lipids mediate steric stabilization, ultimately reducing surface-surface interactions including the aggregation of liposomes and/or adsorption of plasma proteins. The purpose of the studies described here was to compare the effects of PEG-lipid incorporation in liposomes on protein binding, liposome-liposome aggregation and pharmacokinetics in mice. Cholesterol-free liposomes were chosen because of their increasing importance as liposomal delivery systems and their marked sensitivity to protein binding and aggregation. Specifically, liposomes containing various molecular weight PEG-lipids at a variety of molar proportions were analyzed for in vivo clearance, aggregation state (size exclusion chromatography, quasi-elastic light ...

TY - CHAP. T1 - Engineering well-characterized PEG-coated nanoparticles for elucidating biological barriers to drug delivery. AU - Yang,Qi. AU - Lai,Samuel K.. PY - 2017. Y1 - 2017. N2 - Poly(ethylene glycol) (PEG) coatings can substantially reduce nanoparticle uptake and clearance by immune cells as well as nonspecific interactions with the biological environment, thus potentially improving nanoparticle circulation times and biodistribution in target tissues such as tumors. Naturally, the stealth properties of PEG coatings are critically dependent on the density and conformation of surface PEG chains. However, there are significant technical hurdles to both generating sufficiently dense PEG coatings on nanoparticles and precisely characterizing their PEG grafting densities. Here, we describe methods for preparing PEGylated polymeric nanoparticles with precisely tunable PEG coatings without the use of organic solvents, quantifying PEGylation efficiency and density using a standard fluorescence ...
