Aprotinin is a competitive inhibitor of serine proteases, which can inhibit the activity of trypsin, chymotrypsin, kininogenase, etc. Aprotinin can form a stable complex with proteases to block the active sites of the enzymes. Recombinant aprotinin has the same enzymatic properties as animal-derived aprotinin, and can replace animal-derived aprotinin in various biotechnological processes, such as inhibiting the activity of serine proteases in recombinant protein production and cell culture.
Mechanism of Action: Aprotinin can form a stable complex with proteases to block the active sites of the enzymes. Most aprotinin-protease complexes dissociate under conditions of pH < 3.0. Aprotinin binds to proteases in an equimolar effective ratio.
Amino Acid Sequence: Recombinant aprotinin is expressed in recombinant E. coli and purified through multiple column chromatography steps; its amino acid sequence is identical to that of aprotinin derived from bovine lung.
Enzymatic Properties: Recombinant aprotinin has the same enzymatic properties as animal-derived aprotinin, and can replace animal-derived aprotinin in various biotechnological processes.
Usage Instructions:
Aprotinin binds to proteases in an equimolar effective ratio; the recommended binding pH is > 6.0, and no binding occurs under conditions of pH <
3.0.It can be directly dissolved in 0.9% NaCl; after dissolution, it can be stored at -20°C.
Product Advantages:
Animal-origin-free: Produced via recombination, no exogenous virus contamination, and no animal-derived raw materials are used in the production process.
Stable quality: Mass production enables stable and continuous batch production; there is no batch-to-batch variation, and the quality is stable.
High purity: Host protein residues are below the limit requirements for biological products.
Lyophilized powder: Easy to store and transport.
Compliant with regulatory requirements: Production equipment and environment meet relevant regulatory requirements; the production process fully follows the NSF ISO 9001:2015 quality system and complies with GMP guidelines.
Complete quality documentation: Relevant regulatory support documents can be provided according to customer needs.
