Description: L-Glutamic Acid is a non-essential amino acid for human development; referred to as an excitatory amino acid (EAA) due to its role in neurotransmission. Acts as a neurotransmitter at fast synapses; agonist at kainate, NMDA and quisqualate receptors. L-Glutamic acid is one of the two amino acids that contains a carboxylic acid group in its side chains.

Folic acid, also known as folate, is a B vitamin that can be found in a variety of fruits and vegetables. It can also be chemically synthesized. Folate, a watersoluble vitamin, helps the body form red blood cells and aids in the formation of genetic material within every body cell. Folic Acid is a hematopoietic vitamin present, free or combined with one or more additional molecules of L- (+)-glutamic acid, in liver, kidney, mushrooms, spinach, yeast, green leaves, and grasses.
A nutritional delivery form of folate. Folic acid and its derivatives are essential mediators of one-carbon metabolism within cells.

L-Glutamine, the uncharged and amidated analog of L-glutamic acid, is an important amino acid for the incorporation of NH4+ into biomolecules. It is biosynthesized from NH4.
L-Glutamine is an essential amino acid that is a crucial component of culture media that serves as a major energy source for cells in culture.
L-Glutamine is an essential amino acid that is a crucial component of culture media that serves as a major energy source for cells in culture. L-Glutamine is very stable as a dry powder and as a frozen solution. In liquid media or stock solutions, however, L-glutamine degrades relatively rapidly. Optimal cell performance usually requires supplementation of the media with L-glutamine prior to use.

Description: Dextran is a high molecular weight polymer of anhydroglucose. It is composed of approximately 95% alpha-D-(1--<gt/>6) linkages. The remaining a(1--<gt/>3) linkages account for the branching of dextran. Dextran has long and hydrophilic spacer arms that improves the performance of immobilized proteins acting on macromolecules.

Description: Trypan Blue is a blue acid dye with a strong affinity for cellulose containing substrates such as cotton; less affinity for proteinaceous materials. Trypan blue solution may be used in trypan blue based cytotoxicity and proliferation assays.
Trypan Blue is used as a vital dye which is especially important because it is taken up by the reticuloendothelial system. Clark describes assays for the study of teratogenic action of trypan blue on embryonic tissues using Davis and Sauter's fluorescence method and for the staining of collagen, including very fine fibrils, muscle and cornified epithelium using the Van Gieson method. Trypan blue is also recommended for use in dye exclusion procedures for viable cell counting. Non-viable cells will up-take trypan blue at a faster rate than viable cells.

Description: Formaldehyde is used as bactericidal agent. Formaldehyde is used as an embalming agent due to its ability to crosslink primary amino groups in proteins through a methylene linkage; however, due to its extremely toxic nature it tends to be avoided. Formaldehyde is also used in numerous industrial applications and organic syntheses.

Description: Tweens® are a series of nonionic surfactants derived from sorbitan esters. They are soluble or dispersible in water but differ widely in organic and oil solubilities. Used as oil-in-water emulsifiers in pharmaceuticals, cosmetics, cleaning compounds, etc.
Tween® 80 has been widely used in biochemical applications including: solubilizing proteins, isolating nuclei from cells in culture selective protein extraction growing of tubercule bacilli, and emulsifying and dispersing substances in medicinal and food products. It has little or no activity as an anti-bacterial agent. It has been shown to have an adverse effect on the antibacterial effect of methyl paraben and related compounds. Non-ionic detergent used for selective protein extraction and isolation of nuclei from mammalian cell lines.
Soluble/miscible in water to give a clear yellow solution; miscible with alcohol, dioxane, and ethyl acetate; practically insoluble in liquid paraffin and fixed oils (such as mineral oil).
Autoclaving of solutions is not recommended. Sterile filtering is suggested with a 0.22 micron filter. Tween® may need to be warmed to about 40 °C and alternated with portions of hot distilled water while being poured through the filter.
Store at Room Temperature (15-30 °C).

Potassium phosphate is a reagent with high buffering capacity. It occurs in several forms: monobasic, dibasic and tribasic (K3PO4). Most pH neutral potassium phosphate buffer solutions consist of mixtures of the monobasic and dibasic forms to varying degrees, depending on the desired pH.
Potassium phosphate monobasic is typically used as a component for a wide variety of media used in the culture of microorganisms. It is widely used in molecular biology, biochemistry, and chromatography. It is a component in phosphate buffered saline (PBS). In addition to helping maintain pH, it supplies essential phosphate.
