Ethidium bromide intercalates double-stranded DNA and RNA and acts as a frameshift mutagen. It can also be used in conjunction with acridine orange to differentiate between viable, apoptotic and necrotic cells. Ethidium bromide(EtBr) has been used extensively to reduce mitochondrial DNA copy…

Catalase from bovine liver is a homotetrameric enzyme that is primarily located in peroxisomes. Activates the decomposition of hydrogen peroxide Natural antioxidant used to study roles of reactive oxygen species Catalyzes the decomposition of hydrogen peroxide into water and oxygen …

HFBA is a strong acid and an ion-pairing agent. The strong acidity of HFBA ensures that other acidic groups such as carboxylic acid moieties on biomolecules remain protonated, and thus the samples are able to interact with organic solvents in such processes as reverse phase chromatography. The…

Glutaraldehyde is a bifunctional protein cross-linking reagent, reacting with NH2 groups to form Schiff's bases. Sporicidal agent. Glutaraldehyde reacts through cross-linking to impart water resistance to protein and polyhydroxy compounds. It is also a reducing agent for photochemicals. In…

N,N,N',N'-Tetramethylethylenediamine is used to catalyze the formation of free radicals from ammonium persulfate or riboflavin. The free radicals will cause acrylamide and bis-acrylamide to polymerize to form a gel matrix which can be used for sieving macromolecules such as nucleic acids…

Aprotinin is a natural inhibitor of trypsin, chymotrypsin and plasmin. It is found in bovine lymph nodes, lung, parotid gland, spleen, liver, pancreas, seminal vesicles, thyroid gland, kidney, mucous membranes of the trachea and esophagus, ovaries, heart, posterior pituitary and cartilage. A serine…

Squalene, an isoprenoid compound structurally similar to beta-carotene, is an intermediate metabolite in the synthesis of cholesterol. Squalene is not very susceptible to peroxidation and appears to function in the skin as a quencher of singlet oxygen, protecting human skin surface from lipid…
