Downstream processing of recombinant human insulin …
Similarly, in "proinsulin" route of insulin production, the recombinant precursor human insulin/analogue molecules have to be enzymatically cleaved to remove the C-peptide to produce human insulin/analogue heterodimers. In insulin production, enzymatic cleavage most frequently consists of using two enzymes, trypsin and carboxypeptidase B (CPB).
