Bacteriophage inactivation at the air-water-solid interface in dynamic batch systems. (1/492)

Bacteriophages have been widely used as surrogates for human enteric viruses in many studies on virus transport and fate. In this investigation, the fates of three bacteriophages, MS2, R17, and phiX174, were studied in a series of dynamic batch experiments. Both MS2 and R17 readily underwent inactivation in batch experiments where solutions of each phage were percolated through tubes packed with varying ratios of glass and Teflon beads. MS2 and R17 inactivation was the result of exposure to destructive forces at the dynamic air-water-solid interface. phiX174, however, did not undergo inactivation in similar studies, suggesting that this phage does not accumulate at air-water interfaces or is not affected by interfacial forces in the same manner. Other batch experiments showed that MS2 and R17 were increasingly inactivated during mixing in polypropylene tubes as the ionic strength of the solution was raised (phiX174 was not affected). By the addition of Tween 80 to suspensions of MS2 and R17, phage inactivation was prevented. Our data suggest that viral inactivation in simple dynamic batch experiments is dependent upon (i) the presence of a dynamic air-water-solid interface (where the solid is a hydrophobic surface), (ii) the ionic strength of the solution, (iii) the concentration of surface active compounds in the solution, and (iv) the type of virus used.  (+info)

Comparison of immunity generated by nucleic acid-, MF59-, and ISCOM-formulated human immunodeficiency virus type 1 vaccines in Rhesus macaques: evidence for viral clearance. (2/492)

The kinetics of T-helper immune responses generated in 16 mature outbred rhesus monkeys (Macaca mulatta) within a 10-month period by three different human immunodeficiency virus type 1 (HIV-1) vaccine strategies were compared. Immune responses to monomeric recombinant gp120SF2 (rgp120) when the protein was expressed in vivo by DNA immunization or when it was delivered as a subunit protein vaccine formulated either with the MF59 adjuvant or by incorporation into immune-stimulating complexes (ISCOMs) were compared. Virus-neutralizing antibodies (NA) against HIV-1SF2 reached similar titers in the two rgp120SF2 protein-immunized groups, but the responses showed different kinetics, while NA were delayed and their levels were low in the DNA-immunized animals. Antigen-specific gamma interferon (IFN-gamma) T-helper (type 1-like) responses were detected in the DNA-immunized group, but only after the fourth immunization, and the rgp120/MF59 group generated both IFN-gamma and interleukin-4 (IL-4) (type 2-like) responses that appeared after the third immunization. In contrast, rgp120/ISCOM-immunized animals rapidly developed marked IL-2, IFN-gamma (type 1-like), and IL-4 responses that peaked after the second immunization. To determine which type of immune responses correlated with protection from infection, all animals were challenged intravenously with 50 50% infective doses of a rhesus cell-propagated, in vivo-titrated stock of a chimeric simian immunodeficiency virus-HIVSF13 construct. Protection was observed in the two groups receiving the rgp120 subunit vaccines. Half of the animals in the ISCOM group were completely protected from infection. In other subunit vaccinees there was evidence by multiple assays that virus detected at 2 weeks postchallenge was effectively cleared. Early induction of potent type 1- as well as type 2-like T-helper responses induced the most-effective immunity.  (+info)

Purification and characterization from rat kidney membranes of a novel platelet-activating factor (PAF)-dependent transacetylase that catalyzes the hydrolysis of PAF, formation of PAF analogs, and C2-ceramide. (3/492)

We have previously identified two enzyme activities that transfer the acetyl group from platelet-activating factor (PAF) in a CoA-independent manner to lysoplasmalogen or sphingosine in HL-60 cells, endothelial cells, and a variety of rat tissues. These were termed as PAF:lysoplasmalogen (lysophospholipid) transacetylase and PAF:sphingosine transacetylase, respectively. In the present study, we have solubilized and purified this PAF-dependent transacetylase 13,700-fold from rat kidney membranes (mitochondrial plus microsomal membranes) based on the PAF:lysoplasmalogen transacetylase activity. The mitochondria and microsomes were prepared and washed three times, then solubilized with 0.04% Tween 20 at a detergent/protein (w/w) ratio of 0.1. The solubilized fractions from mitochondria and microsomes were combined and subjected to sequential column chromatographies on DEAE-Sepharose, hydroxyapatite, phenyl-Sepharose, and chromatofocusing. The enzyme was further purified by native-polyacrylamide gel electrophoresis (PAGE) and affinity gel matrix in which the competitive inhibitor of the enzyme, 1-O-hexadecyl-2-N-methylcarbamyl-sn-glycero-3-phosphoethanolamine was covalently attached to the CH-Sepharose. On SDS-PAGE, the purified enzyme showed a single homogeneous band with an apparent molecular mass of 40 kDa. The purified enzyme catalyzed transacetylation of the acetyl group not only from PAF to lysoplasmalogen forming plasmalogen analogs of PAF, but also to sphingosine producing N-acetylsphingosine (C2-ceramide). In addition, this enzyme acted as a PAF-acetylhydrolase in the absence of lipid acceptor molecules. These results suggest that PAF-dependent transacetylase is an enzyme that modifies the cellular functions of PAF through generation of other diverse lipid mediators.  (+info)

Enzymatic properties of vesicle-reconstituted human cytochrome P450SCC (CYP11A1) differences in functioning of the mitochondrial electron-transfer chain using human and bovine adrenodoxin and activation by cardiolipin. (4/492)

The recently reported heterologous expression and purification of both human cytochrome P450SCC and adrenodoxin [Woods, S.T., Sadleir, J., Downs, T., Triantopoulos, T., Haedlam, M.J. & Tuckey, R.C. (1998) Arch. Biochem. Biophys. 353, 109-115] has enabled us to perform studies with the membrane-reconstituted human enzymes to better understand the side-chain cleavage reaction in humans. Human P450SCC was successfully reconstituted into dioleoylphosphatidylcholine vesicles with and without cardiolipin and its enzymatic properties characterized in the membrane-bound state. Enhancement of the P450SCC activity and significant activation by cardiolipin were observed when human adrenodoxin instead of bovine adrenodoxin was used as electron donor. In the absence of cardiolipin, Km for cholesterol was decreased twice in the case of human adrenodoxin indicating enhanced cholesterol binding. On the other hand, in the presence of cardiolipin in the membrane both Km and V for cholesterol were decreased with human adrenodoxin as electron donor. Kinetic analysis of the interaction between human P450SCC and its redox partners provided evidence for enhanced binding of the human electron donor to human P450SCC indicated by both an increased V and decreased Kd for human adrenodoxin compared with the values with bovine adrenodoxin. Because no similar effects were observed in Tween 20 micelles, these results suggest that the phospholipid membrane may play an important role in the interaction of human adrenodoxin with human P450SCC.  (+info)

Virus passage through track-etch membranes modified by salinity and a nonionic surfactant. (5/492)

Why do viruses sometimes not pass through larger pores in track-etch filters? Increasing the salinity (0.8 to 160 mM Na+) decreased phiX174 and PRD1 passage through track-etch polycarbonate membranes (sodium dodecyl sulfate coated but not polyvinylpyrrolidone coated) and PRD1 passage through polyester membranes. Undiminished passage when 0.1% Tween 80 was added implied that nonionic virus adsorption occurred and indicated that high levels of salinity decreased virus passage by decreasing electrostatic repulsion that prevented adsorption.  (+info)

Rapid esterase-sensitive breakdown of polysorbate 80 and its impact on the plasma pharmacokinetics of docetaxel and metabolites in mice. (6/492)

We have developed and validated an analytical methodology for the quantification of docetaxel and its four major human oxidation metabolites in mouse plasma. We have used this procedure to study the pharmacokinetics and metabolism of docetaxel in female FVB mice, receiving 2.5, 10, or 33 mg/kg of docetaxel by i.v. injection. We have also studied the pharmacokinetics of polysorbate 80, because it was shown previously that the vehicle substance Cremophor EL, which is used in the formulation of paclitaxel, exerts a profound effect on the pharmacokinetics of this compound. Linear pharmacokinetics of docetaxel was observed at dose levels between 2.5 and 10 mg/kg, where plasma levels corresponded to those in patients receiving the maximum tolerated dose. At the highest dose level of 33 mg/kg, a deviation from the linear kinetics was observed. Compared with humans, mice could tolerate much higher plasma levels, suggesting that the toxic side effects are related to a certain plasma threshold concentration instead of area under the curve or Cmax. At the highest dose level, three docetaxel metabolites could be detected in the plasma samples of mice for up to 4 h after drug administration. The hydroxy metabolite of the tert-butoxy group (metabolite II) was the major metabolite, followed by the two epimeric hydroxyoxazolone-type compounds (metabolites I and III). A fourth putative metabolite (e.g., the cyclic oxazolidinedione derivative) was not detected. Because of rapid degradation of polysorbate 80 by esterases in plasma, the concentration of this vehicle substance declined very rapidly. Consequently, this substance was not able to interfere in the disposition of docetaxel.  (+info)

A novel surfactant nanoemulsion with broad-spectrum sporicidal activity against Bacillus species. (7/492)

Two nontoxic, antimicrobial nanoemulsions, BCTP and BCTP 401, have been developed. These emulsions are composed of detergents and oils in 80% water. BCTP diluted up to 1:1000 inactivated>90% of Bacillus anthracis spores in 4 h and was also sporicidal against three other Bacillus species. This sporicidal activity is due to disruption of the spore coat after initiation of germination without complete outgrowth. BCTP 401 diluted 1:1000 had greater activity than BCTP against Bacillus spores and had an onset of action of <30 min. Mixing BCTP or BCTP 401 with Bacillus cereus prior to subcutaneous injection in mice reduced the resulting skin lesion by 99%. Wound irrigation with BCTP 1 h after spore inoculation yielded a 98% reduction in skin lesion size, and mortality was reduced 3-fold. These nanoemulsion formulas are stable, easily dispersed, nonirritant, and nontoxic compared with other available sporicidal agents.  (+info)

Accumulation of rifampicin by Mycobacterium aurum, Mycobacterium smegmatis and Mycobacterium tuberculosis. (8/492)

The characteristics of the accumulation of 2 mg/L [(14)C]rifampicin by wild-type strains of Mycobacterium aurum (A(+)), Mycobacterium smegmatis (mc(2)155) and Mycobacterium tuberculosis (H37Rv) were determined. After 10 min exposure M. aurum had accumulated 220 ng rifampicin/mg cells, M. smegmatis had accumulated 120 ng rifampicin/mg cells and M. tuberculosis had accumulated 154 ng rifampicin/mg cells. A steady-state concentration (SSC) of rifampicin was accumulated rapidly by M. aurum and M. tuberculosis within minutes of drug exposure, unlike M. smegmatis, which accumulated rifampicin more slowly. With an increase in the concentration of rifampicin from 0.12 mg/L to 2 mg/L there was an increase in the concentration of rifampicin accumulated by M. tuberculosis, with no detectable loss of viability over the 20 min of the accumulation experiment. With an increase in temperature there was also an increase in the concentration of rifampicin accumulated by M. tuberculosis; between 15 and 30 degrees C the increase was linear. For all three species sub-inhibitory concentrations of ethambutol increased the concentration of rifampicin accumulated. However, both growth and accumulation of rifampicin were lower in the presence of 0.05% Tween 80. Accumulation of rifampicin by M. smegmatis was unaffected by the presence of the proton motive force inhibitor, 2,4-dinitrophenol (1 mM), whether added before or after the addition of rifampicin to the mycobacterial culture. For all three species, the Gram-positive bacterial efflux inhibitor reserpine (20 mg/L) slightly increased the SSC of rifampicin, but the increase was not statistically significant. Addition of glucose to energize a putative efflux pump had little effect on the accumulation of rifampicin in the presence or absence of reserpine for M. tuberculosis; however, for M. aurum and M. smegmatis the reserpine effect was abolished by the addition of glucose. These data suggest that rifampicin may be removed from wild-type mycobacteria by efflux, but that the pump(s) is expressed at low level.  (+info)

Safety and immunogenicity of AS03B adjuvanted split virion versus non-adjuvanted whole virion H1N1 influenza vaccine in UK children aged 6 months-12 years: Open-label, randomized, parallel group, multicenter study. The first head to head study of the two H1N1 vaccines used in the UK during the recent pandemic finds that the adjuvanted split virus vaccine induced higher immune response rates in young children, but was associated with more reactions than the whole virus vaccine.. These data provide important information to guide immunisation policy in an influenza pandemic, say the researchers.. During the 2009-10 influenza A (H1N1) pandemic, children experienced pandemic A (H1N1) infections at four times the rate of adults and were more commonly admitted to hospital, making them a priority group for vaccination.. The Department of Health purchased two H1N1 vaccines for the national immunisation programme, an adjuvanted split virion vaccine derived from egg culture and a non-adjuvanted whole ...
misc{7870232, abstract = {The complement system can be activated by three different pathways in the body. It is wanted to be able to detect deficiencies of these activation pathways and Bioporto A/S has acquired the commercial rights to a set of ELISA based assays. There is a need in these commercial assays for optimisation of dilution and wash buffers since the idea with the ELISA kit is to sell it as a ready-to-use kit and the dilution and wash buffer will be stored in small, concentrated volumes. In the concentrated volumes the reagent Tween-20 was a problem since it precipitated with CaCl2 in the buffers. The Tween-20 needed to be replaced and it was found that emulfogen had the same ability as Tween-20 to prevent unwanted binding in the wells without precipitating with CaCl2. Instead of 0,5% Tween-20 in the dilution buffer 0,1% emulfogen could be used and in the wash buffer 0,01% of emulfogen could be used instead of 0,05% Tween-20. Bioporto has also initiated to convert the complement ...

The aqueous environment in the gastrointestinal tract frequently requires solubilization of hydrophobic drug molecules in appropriate drug delivery vehicles. An effective uptake/absorption and systemic exposure of a drug molecule entails many processes, one being transport properties of the vehicles through the mucus layer. The mucus layer is a complex mixture of biological molecules. Among them, mucin is responsible of the gel properties of this layer. In this study, we have investigated the diffusion of polyoxyethylene sorbitane monooleate (polysorbate 80), a commonly used nonionic surfactant, in aqueous solution, in mucin solutions at 0.25 and 5 wt %, and in mucus. These measurements were done by using the pulsed field gradient spin echo nuclear magnetic resonance (PGSE-NMR) technique. We conclude that polysorbate 80 is a mixture of non-surface-active molecules that can diffuse freely through all the systems investigated and of surface-active molecules that form micellar structures with transport

关键词: 单分子FRET, 荧光相关谱, OmpT折叠, Tween-20, DDM Abstract: The cell envelope of gram-negative bacteria consists of the outer membrane (OM), inner membrane (IM), and periplasm. The β-barrel outer membrane proteins (OMPs) embedded in the OM perform diverse and significant functions such as signaling, transporting, and proteolysis. The OMPs of gram-negative bacteria share similar folding pathways with that of mitochondria and chloroplasts. Therefore, the study of the OMP folding mechanism not only provides insights into antimicrobial drug design but also helps elucidate mitochondrial and chloroplast biogenesis. Most knowledge about OMP folding was obtained from ensemble experiments where OMPs were usually at micromolar concentrations and prone to aggregate, which is different from the physiological environment in the cells. Unlike ensemble techniques, single-molecule detection (SMD) can measure OMPs from nano- to picomolar concentrations and prevent aggregation. In this work, ...
with Sorbitan Oleate reduces DNA repair following UV irradiation, but these data were not considered significant in view of the available carcinogenesis data. The Polysorbates were not oral or dermal carcinogens. Data on the cocarcinogenesis of certain Sorbitan Esters were positive, but only with high exposure levels and a high frequency of exposure, and the results lacked a dose-response. The Polysorbates also had antitumor activity in some studies. The Polysorbates had little potential for human skin irritation, sensitization, and phototoxicity in extensive clinical studies. Likewise, PEGs were nonsensitizers, but cases of kidney toxicity were observed in burn patients that were treated with PEG-based topical ointments. Overall, these data were considered an adequate basis for assessing the safety of the entire group of ingredients. The CIR Expert Panel concluded that these ingredients were safe for use in cosmetics at the levels in current use (not more than a 25% concentration) with the ...

Liquid protein formulations are prone to form aggregates. The effect of nonionic surfactants such as Polysorbate 20 (PS 20) and n-Dodecyl β-D-maltoside (DDM) on the prevention of aggregation and conformational changes of recombinant human IFNβ-1b (rhIFN β_1b) was explored. Polysorbate has been used in formulations of protein pharmaceuticals. There have been concerns about using PS 20 due to its residual peroxide content which may negatively affect protein efficacy. n-Dodecyl β-D-maltoside has been of interest and shown to be highly effective in prevention of aggregation. Fresh bulk of rhIFN β_1b was formulated using DDM or different concentrations of PS 20. Formulations were exposed to light stress condition according to the ICH guideline of Q1b. The overall conformational integrity of individual samples was characterized by a combination of Circular dichroism (CD), Fluorescence spectroscopy and RP_HPLC techniques.The CD spectrum depicting the conformational integrity of rhIFN β_1b showed 31.9%

The PBT Assessment for Sorbitan, (Z)-9-octadecenoate (2:3) (CAS No. 8007-43-0) is based on the criteria set out in the Guidance on information requirements and chemical safety assessment, Chapter R.11: PBT Assessment (ECHA, 2012). Persistence The read-across substancesanhydro-D-glucitol trioleate (CAS No. 26266-58-0)is readily biodegradable according to OECD 301 B (84.5% (CO2 evolution) after 28 days). Thus, Sorbitan, (Z)-9-octadecenoate (2:3) (CAS No. 8007-43-0) does not meet the screening criterion for persistency and it is not considered to be P or vP. Bioaccumulation Due to the low water solubility, rapid environmental biodegradation and metabolism via enzymatic hydrolysis of the Sorbitan esters category members, a relevant uptake and bioaccumulation in aquatic organisms is not expected. Enzymatic breakdown will initially lead to the free fatty acid and D-glucitol. From literature it is well known, that these hydrolysis products will be metabolised and excreted in fish effectively ...

II) Wash the membrane twice for 10 minutes each, at room temperature, in 1x TBS, 0.05% Tween-20. Use a large volume (10-20 ml) of buffer for each wash. III) Block the membrane for 1 hour at room temperature, or overnight at 4°C, in 1x TBS, 5% milk, 0.05% Tween-20. Comments: The western blotting procedures are the same for PVDF or nitrocellulose, however the handling of these membranes are different prior to- and during- transfer of proteins from the SDS-PAGE gel to the membrane. Nitrocellulose exhibits the highest sensitivity with very low backgrounds in all transfers, especially in protein blotting. Unlike PVDF, nitrocellulose wets out naturally, does not require methanol, and will not turn hydrophobic during the transfer process. Nitrocellulose is very easily blocked and does not need the many blocking steps required with PVDF. Protocols for Western Blotting with PVDF and Nitrocellulose are the same with a few exceptions. PVDF is hydrophobic and therefore should be prewet in methanol before ...

The study done on rats that found Polysorbate 80 had effects on fertility involved giving 100 mg of Polysorbate 80 to rats that were 4-7 days old. I cant find an exact weight on rats of this age, but I can find that newborn rats weigh 6-8 g. If we even assume that the rats double their birthweight to 12-16 g by 4-7 days old, we are then looking at dosing that is at best 6 mg per GRAM of body weight.. That would be 6000 mg per kg (6g/kg). So dosing that is approximately 2000 times higher than what is given in the Vitamin K injection. I think it is a pretty far stretch to think that these two doses have the same effects. In the particular video I was recently watching, the speaker made a distinction between injected vs injested administration…which is a fair point. But Ill also point out that in the rat study on fertility I linked to above, the Polysorbate 80 was injected into the rats. As far as oral dosing goes, Polysorbate 80 has been used in food products for over 50 years, and was ...
Abstract: The dilational rheological properties of a series of polyoxyethylene sorbitan fatty acid surfactants (TweenX) at the decane/water interface have been investigated using the drop shape analysis method. The experiment results showed that larger quantities of the Tween20 molecules with shorter hydrophobic chain lengths were adsorbed at the interface because they could arrange more closely. Tween40 and Tween60 molecules had similaractual cross-sectional areas, which meant that their interfacial tensions were also similar at the critical micelle concentration (γcmc). Furthermore, when the bulk concentration exceeded the critical micelle concentration (cmc), the modulus and elasticity of Tween20 were larger than those of Tween40 and Tween60. When the hydrophobic alkyl chain of TweenX reached a certain length, the interfacial film properties of TweenX affected by the hydrophobic chain length decreased, which led to similar dilational parameters.. Key words: Polyoxyethylene sorbitan fatty ...

β-elemene, a non-cytotoxic antitumor reagent, inhibits the growth, proliferation and DNA synthesis of multiple types of malignant cells, resulting in the apoptosis or suppressed vascularization of tumors. β-elemene is also able to enhance the immunogenicity of the tumor cells and ameliorate systematic cellular immunity in the tumor‑bearing body. Moreover, β-elemene has the advantages of high efficiency, safety and low possibility of drug tolerance over other antitumor agents used in antitumor treatment. Therefore, β-elemene has great potential in clinical applications. However, the mechanism of β-elemene antitumor activity is largely unknown. The aim of this study was to investigate whether β-elemene is able to repress the proliferation of T24 bladder carcinoma cells through regulation of the expression of the tumor suppressor gene, Smad4. Results of a methylthiazolyl tetrazolium (MTT) assay indicated that the proliferation of T24 cells was repressed by β-elemene in a time- and ...

Methods: HME technique was used to prepare the SLN. The preparation involved 2 main steps; first, the formulation of a suspension by pumping the lipid and drug into the barrel and second was size reduction of the pre-suspension to obtain the nanoparticles (Figure 1). A modified screw configuration was used for the extrusion process. All the lipids used in the study were reported to be safe, biocompatible and biodegradable. The Itraconazole and the lipid (Compritol® 888 ATO/Precirol® ATO 5) was uniformly mixed and introduced into the barrel using the volumetric feeder. The surfactant (Tween® 80) was injected in the barrel using the peristaltic pump. The feeding rates of a volumetric feeder and peristaltic pump were optimized. The pre-suspension obtained was subjected to sonication for size reduction. The prepared formulation was assessed for particle size analysis, zeta potential, viscosity, entrapment efficiency, drug content, in vitro drug release, Transmission Electron Microscopy and ...
Well-defined mechanistic principles have emerged to rationalize micellar enhancement of chemiluminescence. The review of Lin and Yamada[1] focuses on how micelles may be used to improve chemiluminescence signals by changes that affect the reaction rate. These occur in the microenvironment (i.e. polarity, viscosity and/or acidity, etc.), in the chemical and photophysical pathway and in the solubilization, concentration and organization of the solute/reactant. We shall now use these principles as a framework for discussing this work and it will become clear that they are highly inter-related rather than mutually exclusive.[2]. There follow examples of micellar enhancement which have been explained by changes in the microenvironment. In the interaction of sulfite groups in drugs with dissolved oxygen in presence of acidic rhodamine 6G, the surfactant Tween 60 can enhance chemiluminescence by 200%, attributable to a microenvironment that leads to an increase in the fluorescence quantum yield of ...

With exception of the biodegradable liquid nanoparticles, all nanoparticles smaller than 100 nanometer (nm) have to be indicated as nanomaterial. The alcohol contents of nanodispersal sera and active agent concentrates often are supposed to have dehydrating effects. Since concentrations are low and the evaporation rate high, alcohol is insignificant in this context. Due to the presence of alcohol however no allergenic preservatives are required. Washout effects, by contrast, are caused by the tensidic components used in combination with nanocrystals. They can be identified in the INCI by denominations as for instance polysorbate 20, polysorbate 80, caprylyl/capryl glucoside, coco-glucoside, lauryl glucoside and decyl glucoside. They are polyethylene glycols (PEG) and sugar tensides which also are components of cleansing gels („rinse-off preparations). Washout effect means that the emulsifiers or tensides contained in skin care products (leave-on preparations) virtually leach out the skin. ...

But experimentalists should not get too cocky: the next paper, by Jamie Simpson and collaborators at Monash University, describes some of the things that can go wrong. An STD NMR screen of the antimicrobial target ketopantoate reductase (KPR) using the same Maybridge library of 500 compounds revealed 196 hits! The 47 with the strongest STD signals were then tested in a 1H/15N-HSQC NMR assay, leading to 14 hits, of which 4 gave measurable IC50 values in an enzymatic assay. Unfortunately, follow-up SAR was disappointing, and subsequent experiments revealed that aggregation was to blame: when the biochemical experiments were rerun in the presence of 0.01% Tween-20, only a single fragment gave a measurable IC50 value. The researchers redid their STD-NMR screen in the presence of detergent, resulting in 71 hits, all of which were tested in the biochemical screen. This led to the identification of a new (and fairly potent) hit that had previously been missed. This nicely illustrates the fact that ...
Hi Will! All I can offer is that our system with Western blotting on NC works consistently. I use 5% skim milk in TBST buffer (10 mM Tris-HCl, pH 8.0; 0.15 M NaCl; 0.1% Tween-20) to block, and also use the blocking buffer to dilute the primary and secondary antibody, and for the washing steps between. I use a chemiluminescence detection system, and found at first an unspecific streak on my blot. This turned out to be me applying the strepavidin-AP directly over my blot (after incubation with the biotinylated secondary antibody) instead of to the incubation solution, thus removing my blocking and getting this signature streak *grin*. Hope you iron out your problem soon. ;-) Araluen Will Chiu ,will.chiu at auckland.ac.nz, wrote in message news:20010928103151.16882.qmail at ww02.jatek.com... , Dear All , , I have been experiencing intense spotty backgrounds on my 2D western blot , probed with sera using NC membrane.
