Aprotinin is a protein consisting of 58 amino acids, arranged in a single polypeptide chain that is crosslinked by three disulfide bridges. Aprotinin is found in bovine lymph nodes, lung, parotid gland, spleen, liver, pancreas, seminal vesicles, thyroid gland, kidney, mucous membranes of the…

Suitable for cell adhesion in tissue culture, as well as gel formation, platelet aggregation, and as a substrate for collagenase. Collagen is a group of naturally occurring proteins found in animals, especially in the flesh and connective tissues of vertebrates. It is the main component of…

Angiotensin II is a peptide hormone which plays an important role in the regulation of blood pressure. It stimulates the release of aldosterone from the adrenal gland. It has strong vasoconstrictive effects. Angiotensin II plays an important role in the regulation of blood pressure. It…

EC 3.1.1.4 Active enzyme isolated from bee venom One unit of enzyme hydrolyzes one µmol of Diheptanoyl Thio-PC per minute at 25°C PLA2 catalyzes the hydrolysis of fatty acids at the sn-2 position of glycerophospholipids, yielding a free fatty acid and a lysophospholipid. PLA2…

Bovine serum albumin is a single polypeptide of 67kDa and consists of 59 lysine residues, of which 30-35 have primary amines that can react with crosslinkers for the coupling of peptides. OneQuant ™ BSA The BSA carrier protein is also available as our single use OneQuant ™ vials…

Avidin is a basic glycoprotein consisting of four essentially identical subunits. The combined molecular weight of the subunits is about 66,000. Each subunit is a single polypeptide chain containing 128 amino acid residues with alanine at the N-terminal, glutamic acid at the C-terminal, and a…

Arginine-rich subgroup. Commonly used for chromosome-reconstitution studies. Suitable substrate for protein kinase C.

Collagen is Type I soluble, salt free component of skin, bone, tendon, and other fibrous connective tissues. Type I collagen differs from other collagens by their low lysine hydroxylation and low carbohydrate composition. Collagen breaks down metabolically in the body to release N-telopeptide,…

Coenzyme A is an essential cofactor in enzymatic acetyl transfer reactions. Coenzyme A facilitates removal of lipid peroxides by increasing mobilization of fatty acids, and promote repair of plasma membranes by activating phospholipid synthesis. The principal biologically active forms of…

Avidin is a basic glycoprotein isolated from raw egg white. It exhibits high binding affinity for biotin and is capable of producing biotin deficiency in rats and chicks. It also occurs in the white portion of eggs and the oviducts of birds and amphibia. It is destroyed by cooking or irradiation. …

Keyhole limpet hemocyanin is a widely used carrier protein due to its large molecular mass (4.5x10 5 -1.3x10 7 Da aggregates) and large number of primary amines that can react with cross-linkers for the coupling of peptides. The KLH is supplied as a clear to slightly hazy, bluish solution in…
