Product Description

Aprotinin

Application Notes

Small amounts of aprotinin can be added to tubes of drawn blood to enable laboratory measurement of rapidly degraded proteins such as glucagon. Aprotinin can be labelled with fluorescein isothiocyanate. The conjugate retains its antiproteolytic and carbohydrate-binding properties and has been used as a fluorescent histochemical reagent for staining glycoconjugates (mucosubstances) that are rich in uronic or sialic acids. In cell biology aprotinin is used as an enzyme inhibitor to prevent protein degradation during lysis or homogenization of cells and tissues .

Usage Statement

Research Use Only (RUO). Ready for CE IVD labeling of clinical applications.

Key Applications

Enzyme inhibitor

Biochemical Physiological Actions Aprotinin is a competitive serine protease inhibitor that forms stable complexes with and blocks the active sites of enzyme. This binding is reversible, and most aprotinin-protease complexes will dissociate at extreme pH levels >10 or <3. Structurally, Aprotinin is a monomeric globular protein derived from bovine lung that consists of 58 amino acids, arranged in a single polypeptide chain with three crosslinking disulfide bridges.
