Summary
Synonym: RCPB01
Recombinant carboxypeptidase B (EC 3.4.17.2) is specially used for hydrolysis of terminal end alkaline amino acid(lysine, arginine, histidine) of protein C; it is also called as hydrolytic enzyme of peptidyl -L- lysine (L- arginine) and protaminase. The molecular weight is 35kD, isoelectric point is 6, the optimal pH is 7-9. Its’ activity is competitively inhibited by arginine and lysine, metal ion chelating agents such as EDTA also inhibit the enzyme activity.
Product advantage:
Not from animal source: reorganization producing, no exogenous viruses contamination, such as swine flu virus, porcine parvovirus etc.
High purity: It has no other miscellaneous enzyme activity, it has no other side reaction in enzyme reaction:, it has high yield.
High specific activity:
Electrophoresis Purity: electrophoresis identification of SDS-PAGE, 95%
Stability: It is freeze-dried powder, easy to store and transport
