Rehydration reagent, DeStreak
Supplier: Cytiva
The appearance of streaks that distort 2-D electrophoresis maps is a common problem, occurring most frequently when running gels that contain regions greater than pH 7,0. Increased sample load, increased length of the IPG strip, or using a narrower pH gradient worsens the problem. Extra spots on 2-D gels, caused by non specific oxidation of proteins, is another difficulty encountered when running gels containing basic regions. Both streaking and non specific oxidation result in poorly resolved protein patterns and reduced reproducibility between electrophoresis runs.

Glycine ≥99% for molecular biology
Supplier: MP Biomedicals
Storage: Store at Room Temperature (15-30 °C)
Glycine is a non-essential amino acid. It is only amino acid with no asymmetric carbon and thus is not chiral. It is the major inhibitory neurotransmitter. It is involved in the biosynthesis of the porphyrin rings of hemes and chlorophylls.
Glycine is commonly used in buffer solutions, in electrophoresis and preparative chromatography. A study of the folding of monoclonal antibodies in the presence of glycine and their subsequent purification has been published. The use of glycine in the purification of lipopolysaccharides, lipooligosaccharides, and lipid A has been reported. It is an amino acid for use in cell culture media development applications and existing media formulations. Glycine is commonly used as a component in Tris-glycine and Tris-glycine-SDS running buffers for polyacrylamide gel electrophoresis, a component of Towbin's transfer buffer for Western blots, a buffer substance in cryoenzymology, in osmotic pressure maintenance in isoelectric focusing of erythrocytes, salting-in effect in protein chemistry, and as a buffer component in the coupled phosphatase-kinase reaction for end labelling of restriction fragments. The growth requirements of various microorganisms is reported in the Handbook of Microbiology.
Glycine is a non-chiral amino acid that can be synthesized in the body from the amino acid serine by Serine Hydroxymethyltransferase. Inhibitory neurotransmitter in spinal cord, allosteric regulator of NMDA receptors.

Glycerine ≥99%, clear colourless viscous liquid cell culture reagent
Supplier: MP Biomedicals
Storage: Store at Room Temperature (15 - 30 °C)
Glycerol is used both in sample preparation and gel formation for polyacrylamide gel electrophoresis. Glycerol (5-10%) increases the density of a sample so that the sample will layer at the bottom of a gel’s sample well. Glycerol is also used to aid in casting gradient gels and as a protein stabilizer and storage buffer component. Glycerol is used in the concentration and storage of enzymes. Also prevents back-diffusion and protein samples into the buffer. Ideal for use as a cryoprotectant.

Polyvinyl alcohol (PVA) coated capillaries
Supplier: Agilent
PVA coated capillaries contain a permanently adsorbed layer of polyvinyl alcohol. This coating minimises hydrophobic and electrostatic solute/wall interactions and eliminates electroosmotic flow (EOF). Using a proprietary deposition process, the PVA coating is stable over a wide pHrange, even under basic conditions from 2,5 to 9,5. This stability allows the use of many common CE buffers. Because the silica surface is covered, many proteins and amines can be analysed without the peak tailing found with uncoated capillaries. In addition, since EOF is eliminated, cumbersome washing procedures are unnecessary and migration time reproducibility may be improved.

Tris(hydroxymethyl)aminomethane (TRIS, Trometamol)
Supplier: MP Biomedicals
Tris has been useful as buffers in a wide variety of biological systems. Uses include pH control in vitro and in vivo for body fluids and in buffering systems for electrophoresis applications. Tris has been used as a starting material for polymers, oxazolones (with carboxylic acids) and oxazolidines (with aldehydes). Tris does not precipitate calcium salts and is of value in maintaining solubility of manganese salts. It can be used for the direct standardization of a strong acid solution; the equivalence point can be determined either potentiometrically or by use of a suitable indicator such as 3-(4-Dimethylamino-1-naphthylazo)-4-methoxybenzenesulfonic acid. It is an auxiliary material in pharmaceutical science.

Anti-IgG Goat Antibody (HRP (Horseradish Peroxidase))
Supplier: MP Biomedicals
This product is the lyophilized powder of horseradish peroxidase (HRP)-conjugated goat IgG fraction to rabbit IgG (whole molecule) and buffer salts. Anti-Human IgG is developed in goat using IgG from pooled normal human serum as the immunogen. Whole antiserum is fractionated and then further purified by ion exchange chromatography to provide the IgG fraction of antiserum. This fraction is essentially free of other goat serum proteins. Specificity for human IgG is determined by immunoelectrophoresis (IEP) versus purified human IgA, IgG, IgM, Bence Jones kappa, and Bence Jones lambda myeloma proteins.Identity and purity of the antibody is established by immunoelectrophoresis (IEP), prior to conjugation. Electrophoresis of the antibody preparation followed by diffusion versus anti-goat IgG and anti-goat whole serum result in single arcs of precipitation in the gamma region.
