RECOMBINANT CARBOXYPEPTIDASE B

RECOMBINANT TRYPSIN

FOR MANUFACTURING OF RECOMBINANT HUMAN INSULIN

Animal Origin Free, No Virus Contaminant

ANIMAL ORIGIN FREE

In the past 20 years, there has been a shift away from using bovine- or porcine-derived insulin to recombinant human insulin. Recombinant human insulin is generally AOF level 1 component due to the usage of bovine- or porcine-derived trypsin and carboxypeptidase B in its manufacturing. However, as worries about animal origin contaminants have increased, many biopharmaceutical companies have begun to consider producing AOF level 2 or AOF level 3 insulin. YaxinBio offers recombinant trypsin and recombinant carboxypeptidase B as essential components for the AOF level 3 insulin production. The value addition and safety offered in this AOF level 3 version provides a tremendous advantage to insulin manufacturers to fetch better market price in already crowded and pricesensitive insulin market-place.
