Zinc electrowinning from acidic sulfate solutions Part I: Effects of sodium lauryl sulfate - Murdoch Research Repository
The effects of sodium lauryl sulphate(SLS) in the presence and absence of antimony(III) on the current efficiency, power consumption and polarization behaviour of zinc were determined. The surface morphologies and deposit crystallographic orientations were also evaluated. The results were compared with glue as the addition agent. The addition of sodium lauryl sulfate to the zinc sulfate solution increased current efficiency, reduced power consumption and improved the surface morphology. Maximum current efficiency and minimum power consumption were achieved on addition of 0.02 mg dm-3 Sb with 1 mg dm-3 sodium lauryl sulfate.. ...

Ionic Detergents › Detergenzien › Infopunkt › SERVA Electrophoresis GmbH
For example, the anionic detergent sodium dodecyl sulfate (SDS) carries a negatively charged sulfate group on a linear C12 hydrocarbon chain. SDS is considered as a very strong and biologically harsh surfactant. It is able to denature proteins by breaking intra- and intermolecular interactions and thus destroying their biological activity. Other anionic detergents like the bile acid salts Na-cholate and Na-deoxycholate have a rigid steroidal core structure. They do not carry a well defined polar head group opposite to a hydrophobic tail (such as SDS). The polar groups are distributed on different parts of the molecule, resulting in a polar and non-polar side, e.g. Na-deoxycholate carries a carboxylate group at the end of a short hydrocarbon chain and two hydroxyl groups on the steroid structure. The bile acids are less denaturing than the ionic alkyl detergents, possibly due to their rigid steroidal ring structure.. Cationic detergents have a positively charged head group, which is often a ...
Sodium Lauryl Sulfate, a Microbicide Effective Against Enveloped and Nonenveloped Viruses | BenthamScience
Title: Sodium Lauryl Sulfate, a Microbicide Effective Against Enveloped and Nonenveloped Viruses. VOLUME: 3 ISSUE: 1. Author(s): J. Piret, A. Desormeaux and M.G. Bergeron. Affiliation:Centre de Recherche en Infectiologie, Centre Hospitalier Universitaire de Quebec, Pavillon CHUL,2705 Blvd Laurier, Quebec, QC, Canada G1V 4G2.. Abstract: The number of individuals infected with human immunodeficiency virus (HIV) and other pathogens causing sexually transmitted diseases (STDs) is growing dramatically worldwide. Globally, heterosexual transmission may account for as much as 85-90% of new cases of HIV infection. Latex condoms represent an effective barrier against sexually transmitted pathogens, but unfortunately, their use is not generalized. Therefore, there is an urgent need to develop safe and potent topical microbicides under the control of women to efficiently reduce the spread of sexually transmitted infections. Sodium lauryl sulfate (SLS), an anionic surfactant with protein denaturing potency, ...

20.109(S21):M1D4 - Course Wiki
Today we will harvest plasmid DNA from E. coli using a purification method called alkaline lysis. In the last lab section, for yeast there needs to be one additional step to help break down the cell wall, but overall goal of each step is the same between both purification protocols--separate the plasmid DNA from the chromosomal DNA and cellular debris, allowing the plasmid DNA to be studied further. The key difference between plasmid DNA and chromosomal DNA is size and this difference is what is used to separate the two components. In this protocol the media is removed from the cells by centrifugation. The cells are first resuspended in a solution that contains Tris, to buffer the cells, and EDTA to bind divalent cations in the lipid bilayer, thereby weakening the cell envelope. Second an alkaline (basic) lysis buffer is added that contains sodium hydroxide and the detergent sodium dodecyl sulfate (SDS). The base denatures the cells DNA, both chromosomal and plasmid, while the detergent ...
Alkaline lysis - Wikipedia
Alkaline lysis or alkaline extraction is a method used in molecular biology to isolate plasmid DNA from bacteria. Bacteria containing the plasmid of interest are first cultured, then a sample is centrifuged in order to concentrate cellular material (including DNA) into a pellet at the bottom of the containing vessel. The supernatant is discarded, and the pellet is then re-suspended in an EDTA-containing physiological buffer. The purpose of the EDTA is to chelate divalent metal cations such as Mg2+ and Ca2+, which are required for the function of DNA degrading enzymes (DNAses) and also serve to stabilise the DNA phosphate backbone and cell wall. Glucose in the buffer will maintain the osmotic pressure of the cell in order to prevent the cell from bursting. Tris in the buffer will retain the pH of the cell with 8.0 and RNase will remove the RNA which will disrupt the experiment. Separately, a strong alkaline solution consisting of the detergent sodium dodecyl sulfate (SDS) and a strong base such ...
Sodium lauryl sulfate - DrugBank
Sodium Lauryl Sulfate (SLS) is an anionic surfactant naturally derived from coconut and/or palm kernel oil. It usually consists of a mixture of sodium alkyl sulfates, mainly the lauryl. SLS lowers surface tension of aqueous solutions and is used as fat emulsifier, wetting agent, and detergent in cosmetics, pharmaceuticals and toothpastes. It is also used in creams and pastes to properly disperse the ingredients and as research tool in protein biochemistry. SLS also has some microbicidal activity.

Pharmaceutics | Free Full-Text | Influence of Sodium Lauryl Sulfate and Tween 80 on Carbamazepine-Nicotinamide Cocrystal...
The influence of the surfactants of sodium lauryl sulfate (SLS) and Tween 80 on carbamazepine-nicotinamide (CBZ-NIC) cocrystal solubility and dissolution behaviour has been studied in this work. The solubility of the CBZ-NIC cocrystal was determined by measuring the eutectic concentrations of the drug and the coformer. Evolution of the intrinsic dissolution rate (IDR) of the CBZ-NIC cocrystal was monitored by the UV imaging dissolution system during dissolution. Experimental results indicated that SLS and Tween 80 had little influence upon the solubility of the CBZ-NIC cocrystal but they had totally opposite effects on the IDR of the CBZ-NIC cocrystal during dissolution. SLS significantly increased the IDR of the CBZ-NIC cocrystal while Tween 80 decreased its IDR.
Sodium Lauryl Sulfate
Sodium Lauryl Sulfate is useful in a wide variety of personal care applications in which viscosity building and foam characteristics are of importance. Because of its low salt content, this product is particularly useful in formulations that are sensitive to high levels of sodium chloride. It is compatible with alkanolamides and amphoterics so that maximum optimization of foam and viscosity characteristics can be reached in the finished product. It can be incorporated into shampoos, handsoaps, bath products, shaving creams and medicated ointments. It is especially useful for opaque, pearlescent, or cream products.

Mucin-chitosan complexes at the solid-liquid interface: Multilayer formation and stability in surfactant solutions
The adsorption of a biologically important glycoprotein, mucin, and mucin-chitosan complex layer formation on negatively charged surfaces, silica and mica, have been investigated employing ellipsometry, the interferometric surface apparatus, and atomic force microscopy techniques. Particular attention has been paid to the effect of an anionic surfactant sodium, dodecyl sulfate (SDS), with respect to the stability of the adsorption layers. It has been shown that mucin adsorbs on negatively charged surfaces to form highly hydrated layers. Such mucin layers readily associate with surfactants and are easily removed from the surfaces by rinsing with solutions of SDS at concentrations ≥0.2 cmc (1 cmc SDS in 30 mM NaCl is equal to 3.3 mM). The mucin adsorption layer is negatively charged, and we show how a positively charged polyelectrolyte, chitosan, associates with the preadsorbed mucin to form mucin-chitosan complexes that resist desorption by SDS even at SDS concentrations as high as 1 cmc. Thus, ...

How to measure total protein conc. of cultured-cell lysate?
Hellow I wanted to thank all those who responded--privatly and on this beautiful newsgroup--to my help request. In addition, I used the BCA method from Pierce successfully. I have to make BSA standards in the same buffer solution and do 5 folds dilution. That is taking the SDS concentration to 0.4% in all sample and standards. I added the other components of the SDS gel loading buffer (DTT and BrPhenol Blue) after Im satisfied with the measurments. ----- From my small experience, direct UV measurment is not reliable, the presence of 1% SDS does not allow direct total protein measurment using Peirce BCAs nor Biorads kits.

Round-Up: The Best Sulfate-Free Products - Fashionista
Sulfates have been steadily gaining a bad rep in the beauty industry for the last few years. Why and what the heck are they?
Sodium lauryl sulfate, ammonium lauryl sulfate and others are found in basically any cleaning product that lathers and foams: soaps, shampoos, bubble bath, toothpaste, and yes, oven cleaner. Heres whats known about sulfates:
1) They can irritate the scalp, skin, and eyes.
2)They strip the essential oils from hair, which is what gives you that squeaky clean feeling. But they also cause the hair to dry out and can lead to breaking and damage.
3) They can cause allergic reactions.
4) Theyre bad for the environment (they can kill fresh water fish) and dont break down easily.
5) The jury is still out on whether theyre carcinogens. Recent studies have shown that sulfates are safe to be applied or consumed, but other studies have shown that they turn into a carcinogen when combined with other chemicals. (Some of which, yes, are also found in shampoos). The FDA isnt all

Structural studies on individual components of bovine transferrin | Biochemical Journal
The single-banding components of bovine transferrin from animals homozygous for the four transferrin variants found in the U.K. were isolated. Sedimentation equilibrium ultracentrifugation and sodium dodecyl sulphate-polyacrylamide-gel electrophoresis showed that the bands of a single variant have molecular weights of 77500 and 73300 respectively. The different bands of a single variant and single bands of different variants show no evidence of size heterogeneity or of low-molecular-weight peptides being split off after reduction in 6m-guanidine hydrochloride. The two slower bands of a single variant, which both contain 2 molecules of sialic acid/molecule of protein, have the same molecular weight and amino acid composition, and give identical peptide maps, although differences in composition and peptide maps occur between the different variants. The results support the concept that bovine transferrin is essentially a single polypeptide chain, but they do not explain differences in ...

The removal of crystal violet from aqueous solution by NiFe2O4 magnetic nanoparticles treated with sodium dodecyl sulfate was investigated. The modified magnetic nanoparticles were prepared by chemical reaction of a mixture of Ni+2 and Fe+3 ions mixture in aqueous solution at the presence of ammonia and then sodium dodecyl sulfate was utilized as an ionic surfactant to modified the obtained magnetic nanoparticles. The morphologies of synthesized magnetic nanoparticles was characterized by electron microscopy techniques. The X-ray diffraction results confirmed the formation of magnetic nanoparticles with face centred cubic structure and the crystallite size was found to be 19 nm. The Fourier transform infrared spectrums confirmed the coating of sodium dodecyl sulfate on synthesized magnetic nanoparticles. The effects of different parameters, such as pH, initial concentration of dye and contact time were studied on the adsorption of crystal violet onto modified magnetic nanoparticles.

Particles with tunable porosity and morphology by controlling interfacial instability in block copolymer emulsions | www.icb...
A series of porous block copolymer (BCP) particles with controllable morphology and pore sizes was fabricated by tuning the interfacial behavior of BCP droplets in oil-in-water emulsions. A synergistic adsorption of polystyrene-b-poly(4-vinylpyridine) (PS-b-P4VP) BCPs and sodium dodecyl sulfate (SDS) to the surface of the emulsion droplet induced a dramatic decrease in the interfacial tension and generated interfacial instability at the particle surface. In particular, the SDS concentration and the P4VP volume fraction of PS-b-P4VP were key parameters in determining the degree of interfacial instability, leading to different types of particles including micelles, capsules, closed-porosity particles, and open-porosity particles with tunable pore sizes ranging from 10 to 500 nm. The particles with open-porosity could be used as pH- responsive, high capacity delivery systems where the uptake and release of multiple dyes could be achieved.. ...

Yeast require an Intact Tryptophan Biosynthesis Pathway and Exogenous Tryptophan for Resistance to Sodium Dodecyl Sulfate ...
Sodium Dodecyl Sulfate, or SDS, is an anionic detergent with widespread use in industrial and household cleaning products, scientific laboratories, and personal care products such as toothpaste and shampoo. The potential toxicity of SDS has been well-characterized in whole organism studies and its potential effects on the environment continue to be studied. Herein, we undertake a chemical-genetic screen to explore whether low concentrations of SDS have any discernible effects at the cellular level. Our screen of the homozygous diploid yeast deletion collection identified numerous gene deletions that confer sensitivity to SDS. Subsequent bioinformatic and biological analyses reveal that yeast unable to synthesize tryptophan are especially sensitive to the presence of SDS. Interestingly, even wild-type yeast with an intact tryptophan biosynthetic pathway exhibit growth defects in the presence of SDS on media lacking tryptophan. Altogether, we have shown that low levels of SDS, primarily through ...

Studies on the separation of hydronium ion using surfactant-modified reversed-phase stationary phases and eluents containing an...
A further investigation of a chromatographic system allowing determination of hydrogen ions is reported. For this purpose an octadecylsilica column dynamically modified with sodium dodecylsulfate (SDS) or lithium dodecylsulfate (LDS) was used as stationary phase and a slightly acidified electrolyte (usually KCl)-SDS solution was used as the eluent. The concentration of SDS, KCl and the acidity of the eluent affected the structure of aggregates formed by the molecules of dodecylsulfate at the surface of the stationary phase. These aggregates of dodecylsulfate were found to be responsible for the appearance of a chromatographic peak attributed to the presence of H3O+ ions in a sample. Other cations in the sample could be separated in the same manner, permitting the simultaneous separation of monovalent cations from H3O+. The detection limit for H3O+ ions was 2.25·10−6 M using an eluent comprising 0.3 mM LDS, 50.0 mM KCl and 0.10 mM H2SO4. The proposed method is shown to be applicable for the ...

SDS micelles
Aniara Sodium Dodecyl Sulphate, 0.5 g (1000 tablets)
Anionic detergent that denatures secondary and non-disulfide-linked tertiary protein structures. Applies a negative charge to each protein in proportion to its mass. SDS binds in a ratio of approximately 1.4 g SDS per 1.0 g protein, unfolding it to give a near-uniform negative charge along the length of the polypeptide chain. As a result, the distance of migration through the gel in SDS-PAGE electrophoresis can be assumed to be directly related only to the size of the protein. More than 99% pure. One tablet weighs 0.5 g and can be dissolved in deionized water to the desired volume.
Introverted Wife: Picture a Day - Day 212
Special toothpaste designed for all of us canker sore sufferers. The sad thing is that what makes it so special isnt whats in it but whats left out - SLS to be exact. SLS (or sodium lauryl sulfate) is what causes the foaming reaction you get with toothpastes, it also causes small microscopic tears in your mouth (which considering what I use it for in the lab it makes a lot of sense ...
