Protease from Staphylococcus aureus strain V8 is composed of a single polypeptide chain. The Staphylococcus strain V8 protease specifically cleaves peptide bonds on the carboxyl (COOH) terminal side of aspartic and glutamic acid residues. Protease V8 is used for selective cleavage of proteins…

AEBSF hydrochloride is a covalent binding serine protease inhibitor, belongs to the family of irreversible sulfonyl fluoride inhibitors that block trypsin and chymotrypsin-type enzymes. Similar in structure to the commonly used inhibitor PMSF, AEBSF offers better solubility in water, lower…

Ribonuclease belongs to pancreatic ribonuclease family. RNase A is an endoribonuclease that attacks at the 3¢ phosphate of a pyrimidine nucleotide. The sequence of pG-pG-pC-pA-pG will be cleaved to give pG-pG-pCp and A-pG. Ribonuclease A is used to remove RNA from DNA plasmid preparations…

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 metabolized in the tricarboxylic acid cycle to produce…

α-Amylase isolated from porcine pancreas is a glycoprotein. It is a single polypeptide chain of ~475 residues containing two SH groups and four disulfide bridges and a tightly bound Ca2+ necessary for stability. Chloride ions are necessary for activity and stability. α-Amylase is…

Elastase is an enzyme from the class of proteases (peptidases) that break down proteins. It hydrolyzes peptide bonds, especially those adjacent to neutral amino acids. Hydrolyses elastin Digests hemoglobin, casein, and fibrin One unit will solublize 1 mg of elastin in 20 minutes at…

Horseradish peroxidase is used for production of peroxidase conjugated antisera. It is a widely used label for immunoglobulins in many different immunochemistry applications including ELISA, immunoblotting, and immunohistochemistry. HRP can be conjugated to antibodies by several different methods…

Cell-permeable, reversible, substrate competitive tyrosine kinase inhibitor (including EGFR phosphorylation), implicated in almost all cell growth and proliferation signal cascades. Inhibitor of mammalian DNA topoisomerase II. Anticancer agent, inducing cell cycle arrest and apoptosis.…

Deoxyribonuclease from beef pancreas, DNase I, was first crystallized by Kunitz. It is an endonuclease which splits phosphodiester linkages, preferentially adjacent to a pyrimidine nucleotide yielding 5'-phosphate terminated polynucleotides with a free hydroxyl group on position 3'. The…

An antineoplastic of Rhodomycin group; Antibiotic; Inhibitor of enzymes and metabolic pathways. A potent anticancer agent that has been shown to be a strong inhibitor of DNA and RNA synthesis. Daunorubicin hydrochloride is used in photostability , antileukemic, and drug metabolism studies. …

The AMC fluorogenic substrates are widely used for routine assays of peptidases. A short peptide sequence is conjugated to 7-AMINO-4-METHYLCOUMARIN, which is released upon cleavage by peptidase. The release of 7-AMINO-4-METHYLCOUMARIN is then measured spectrophotometrically. The excitation; 380 nm…

Acetoacetyl coenzyme A (Acetoacetyl-CoA) may be used as a substrate for a number of enzymes including; acetoacetyl-CoA thiolase (EC 2.3.1) which produces acetyl-CoA in reverse condensation reaction and (3-Hydroxy-3-methylglutaryl coenzyme A (CoA) synthase (HMGCS)) which produces…

Pepstatin A is a reversible inhibitor of aspartic proteases, Inhibitor for pepsin, renin, cathepsin D, cathepsin G, and other acid proteases. It does not inhibit thiol proteases, neutral proteases or serine proteases. Pepstatin forms a 1:1 complex with acid proteases (carboxyl proteases). …

Proteinase K is a highly active stable endopeptidase with a broad spectrum of action was isolated by E. Merk's Darmstadt Biochemical Research Department in 1970 from a culture filtrate of the fungus, Tritirachium album Limber. This fungus is able to grow on Keratin (e.g., wool, horn particles)…

Ribavarin is an antiviral compound reported to be active against RSV, HIV, HCV and other infectious agents. Its metabolite, ribavirin 5'-phosphate, inhibits inosine monophosphate dehydrogenase (IMP). It is also an analog of the imidazole nucleotide intermediates in purine nucleotide…

Cell permeable fungal toxin that disrupts contractile microfilaments by inhibiting actin polymerization. This, in turn, induces DNA fragmentation, inhibits cell division, and disrupts many cell processes. Inhibits glucose transport. One of a group of fungal metabolites that interfere with a wide…

E-64 is an inhibitor for thiol protease, papain, actinidin, ananain, bromelain, calpain and cathepsin B.
