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.

D-myo-Inositol is a component of membrane phospholipids, glycosylphophatidylinositol anchors that bind glycoproteins to cell membranes, and inositol phosphate second messengers. It is a growth factor for animals as well as microorganisms. Myo-Inositol is the most abundant form of polyols that serves as a structural element of secondary messengers in eukaryotic cells. Inositol or cyclohexane-1,2,3,4,5,6-hexol is a chemical compound, a sixfold alcohol (polyol) of cyclohexane. It exists in nine possible stereoisomers, of which the most prominent form, widely occurring in nature, is cis-1,2,3,5-trans-4,6-cyclohexanehexol, or myo-inositol (former name meso-inositol). Inositol is a carbohydrate, though not a classical sugar. It has a taste which has been assayed at half the sweetness of table sugar. Used as a lipotropic agent.
A component of membrane phospholipids, glycosyl­phosphatidyl­inositol anchors that bind glycoproteins to cell membranes, and inositol phosphate second messengers. In addition, inositol serves as an important component of the structural lipids phosphatidylinositol (PI) and its various phosphates, the phosphatidylinositol phosphate (PIP) lipids.

Adenosine 5'-triphosphate (ATP) and its phosphate bonds are the basic components of energy exchange in many biological systems.
Adenosine 5'-triphosphate (ATP) is a central component of energy storage and metabolism in vivo. ATP is used in many cellular processes, respiration, biosynthetic reactions, motility, and cell division. ATP is a substrate of many kinases involved in cell signaling and of adenylate cyclase(s) that produce the second messenger cAMP. ATP provides the metabolic energy to drive metabolic pumps. ATP serves as a coenzyme in a wide array of enzymatic reactions.
P2 purinergic agonist; increases activity of Ca2+-activated K+ channels; substrate for ATP-dependent enzyme systems.

Beschreibung: Amersham™ ECL™ Prime ist ein hochsensitives Western Blotting Detektionsreagenz, das sich durch eine stabile Signalemission auszeichnet. Dies ermöglicht mehrere Belichtungen und macht es einfacher, mehrere Blots in einem Experiment parallel zu verarbeiten. Amersham™ ECL™ Prime bietet ein Detektionssystem, das über einen breiten dynamischen Bereich von Proteinmengen hinweg empfindlich, stabil und präzise quantitativ ist und sich gleichzeitig durch den niedrigen Verbrauch der teuren Antikörperreagenzien auszeichnet. Die hohe Leistung des Amersham™ ECL™ Prime ist einem Enhancer im Reagenz zu verdanken, der den Enzymumsatz steigert und somit die Signalintensität und -dauer deutlich erhöht. Das Lichtsignal wird durch Zugabe eines Katalysators weiter intensiviert.

Protamine sulfate is a purified mixture of simple protein principles obtained from the sperm or testes of suitable species of fish, which has the property of neutralizing heparin. Because of having many basic amino acids (mostly arginine) protamine contains far greater nitrogen than other proteins. Its molecular weight is relatively small. Histone and other basic proteins in the testes of unmatured fishes convert into protamine along with the growth of the fishes. In the testes, protamine takes the form of nucleoprotamine linked with DNA.
Protamine Sulfate is a raw material for study preparations like insulin compounds, and etc. It is used in separation and refining of vaccines. It is a reagent for removing nucleic acids from enzyme solution for the purpose of easy separation and refining. Protamine in the form of solid lipid nanoparticles (SLN) promoted transfection with plasmid DNA more efficiently and with less cytotoxicity than comparable SLNs composed of Esterquat-1.
Protamine sulfate is a small cationic protein that binds and precipitates DNA. Inhibits lipoprotein lipase. Protamine sulfate shown to inhibit the classical pathway of complement. It inhibits turnover of lipoproteins by lipoprotein lipase.

D-Biotin is a growth factor present in small amounts in every living cell. It is involved in naturally occurring carboxylation reactions. It occurs mainly bound to proteins or polypeptides. It is more abundant in the liver, kidney, pancreas, yeast and milk. Biotin levels are higher in cancerous tumors than in normal tissues. It is inactivated by binding to avidin.
D-Biotin may be used to elute proteins from avidin/streptavidin resins. It is widely used for dietary supplements and fortified foods. It is also used for tablets and hard-shell capsule preparation due to its pharmaceutical properties.
Essential vitamin that is important for amino acid and energy metabolism, and fatty acid synthesis. It is a prosthetic group in four mammalian carboxylase families and facilitates the binding and transfer of carbon dioxide.

Pyruvic acid is an intermediate in sugar metabolism and in enzymatic carbohydrate degradation (alcoholic fermentation) where it is converted to acetaldehyde and CO2 by carboxylase. In muscle, pyruvic acid (derived from glycogen) is reduced to lactic acid during exertion, which is reoxidized and partially retransformed to glycogen during rest. It improves coliform recovery when present in culture medium. It is involved in a metabolic regulatory pathway activated by mitochondrial oxidants. Pyruvate is involved in respiratory regulation in plants by interacting with alternative oxidase at a conserved cysteine residue. It may help prevent hydrogen peroxide mediated cell death.
Sodium pyruvate is utilized as a component in culture broth and media. Sodium pyruvate is used in Wallen fermentation medium to enhance the conversion of oleic acid to 10-ketostearic acid by Bacillus sphaericus. Sodium pyruvate has also been used to establish stably transfected human B cell lines.
Sodium Pyruvate has shown antioxidant properties and protective effects against oxygen radicals. Pyruvate is produced as part of glycolysis and is an intermediate in many metabolic pathways. It can be converted into acetyl CoA and enter the TCA Cycle.

Glutathione is the major low molecular weight thiol compound of the living plant or animal cell. It is a tripeptide with a gamma peptide linkage between the amine group of cysteine (which is attached by normal peptide linkage to a glycine) and the carboxyl group of the glutamate side-chain. It is an antioxidant, preventing damage to important cellular components caused by reactive oxygen species such as free radicals and peroxides. The sulfhydryl (thiol) group (SH) of cysteine serves as a proton donor and is responsible for the biological activity of glutathione.
Glutathione suppresses human immunodeficiency virus expression in chronically infected monocytic cells. It is a useful tripeptide involved in many aspects of metabolism, including transport of g-glutanyl amino acids and reductive cleavage of disulfide bonds.
Endogenous antioxidant that plays a major role in reducing reactive oxygen species formed during cellular metabolism and the respiratory burst. Glutathione-S-transferase catalyzes the formation of glutathione thioethers with xenobiotics, leukotrienes, and other molecules that have an electrophilic center. Glutathione also forms disulfide bonds with cysteine residues in proteins. Via these mechanisms, it can have the paradoxical effect of reducing the efficacy of anti-cancer agents.
