A thymosin alpha-1 concatemer (multiple linked copies) was expressed in E. coli and cleaved to release multiple active peptides per expression event, dramatically improving manufacturing yield.
Key findingThymosin alpha-1 concatemer expression in E. coli produced multiple peptide copies per fusion protein, with enzymatic cleavage releasing biologically
What the researchers found
Thymosin alpha-1 concatemer expression in E. coli produced multiple peptide copies per fusion protein, with enzymatic cleavage releasing biologically active thymosin alpha-1 — a high-yield manufacturing strategy for this clinical peptide drug.
