Aprotinin is a single chain polypeptide (58 amino-acids) crosslinked by three disulfide bridges, showing competitive and reversible inhibiton of proteolytic and esterolytic activity. Aprotinin forms stable complexes with, and blocks the active sites of serine protease enzymes. 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.
Aprotinin is a competitive serine protease inhibitor that inhibits trypsin, chymotrypsin, kallikrein and plasmin. Aprotinin forms stable complexes with and blocks the active sites of enzymes. Binding is reversible with most aprotinin-protease complexes dissociating at pH >10 or < 3.

Aprotinin is used as a proteolytic inhibitor in radioimmunoassays of polypeptide hormones.

Sulfobromophthalein (BSP) is a dye with a high affinity for organic anion transporting polypeptides (OATPs) and has been used as a substrate for multidrug resistance associated protein 2 (Mrp2). BSP is transported into hepatocytes by OATPs and, after conjugation to glutathione, is excreted into bile by Mrp2. It was found to inhibit the aldo-keto reductase ARK1C20.
Sulfobromophthalein (BSP) is used in diagnosis of hepatic disorders. It is also used for the quantitative determination of proteins.

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 carbohydrate moiety attached at the aspariginyl residue, position 17. It is 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.

The protein encoded by FGA gene is the alpha component of fibrinogen, a blood-borne glycoprotein comprised of three pairs of nonidentical polypeptide chains. Following vascular injury, fibrinogen is cleaved by thrombin to form fibrin which is the most abundant component of blood clots. In addition, various cleavage products of fibrinogen and fibrin regulate cell adhesion and spreading, display vasoconstrictor and chemotactic activities, and are mitogens for several cell types. Mutations in this gene lead to several disorders, including dysfibrinogenemia, hypofibrinogenemia, afibrinogenemia and renal amyloidosis. Alternative splicing results in two isoforms which vary in the carboxy-terminus.

The total protein is measured using the Biuret procedure with bovine albumin as the standard. To ensure that the product titer falls within the required range, antibody titer is standardized by microtiter plate ELISA with human fibrinogen. The product is tested for purity and specificity at final concentration by immunoelectrophoresis. The antibody is predominantly goat IgG; no trace of albumin is detected.

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.
