3-(4,5-Dimethylthiazolyl-2)-2,5-Diphenyl Tetrazolium Bromide(MTT) is an histochemical/cytochemical reagent. It is converted to water-insoluble MTT-formazan of dark blue color by mitochondrial dehydrogenases of living cells, thus used for measurement of cell division.

Supplier: MACHEREY-NAGEL

Cyclodextrin modified silica phases for HPLC enantiomer separation. These phases are especially suited for the control of optical purity and for the analysis of positional and cis-trans isomers.

Supplier: MP Biomedicals

Soluble in acetone and in methanol (5 mg/ml) yielding a clear to very slightly hazy, yellow to amber solution. Gossypol is insoluble in water, very slightly soluble in petroleum ether and soluble in ethanol, ether, chloroform and DMF. It is freely soluble (with slow decomposition) in dilute aqueous solutions of ammonia and sodium carbonate.

Amphotericin B is a polyene antifungal antibiotic from Streptomyces. It has an affinity for sterols, primarily ergosterols, of fungal cell membranes. It forms channels in the membranes, causing small molecules to leak out which contributes to cell death.

Acetyl-CoA is produced via beta-oxidation of fatty acids, via the metabolism of carbohydrates - glucose 6-phosphate to pyruvate to acetyl-CoA and via the catabolism of amino acids. Acetyl-CoA has a number of metabolic opportunities. It is metabolised in the tricarboxylic acid cycle to produce carbon dioxide, water and energy.

3- (4,5-Dimethyl-2-thiazolyl-2)-2,5-diphenyl-tetrazolium bromide is used as a colorimetric metabolic activity indicator in cell viability assays. Thiazolyl Blue Tetrazolium Blue (MTT) is a dye used in measurement of cell proliferation. MTT produces a yellowish solution that is converted to dark blue, water-insoluble MTT formazan by mitochondrial dehydrogenases of living cells. The blue crystals are solubilized with acidified isopropanol and the intensity is measured colorimetrically at 570 nm. MTT has been used as a histochemical/cytochemical reagent and for the detection of NAD. ADP-linked enzyme systems in tissue cannot be detected with MTT, due to binding of the cation by the cyanide trap used. MTT is rapidly reduced to the formazan, which chelates with nickel, copper, and cobalt; the cobalt chelate has been used in oxidative systems.

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.
