Recombinant Carboxypeptidase B (rCPB) GMP Enzyme for Insulin Purification & Bioprocessing

Recombinant Carboxypeptidase B GMP Grade Enzyme API Supplier

Our Recombinant Carboxypeptidase B (rCPB) represents a breakthrough in enzymatic biotechnology, offering pharmaceutical manufacturers a highly pure and efficient solution for precision protein processing. As a zinc-containing exopeptidase, rCPB specifically catalyzes the cleavage of C-terminal basic amino acids (arginine and lysine), making it indispensable in the production of recombinant insulin and other therapeutic proteins. Through advanced recombinant DNA technology, we have engineered a superior enzyme with exceptional catalytic efficiency, thermal stability, and lot-to-lot consistency that far exceeds traditional pancreatic extracts.

Manufactured under stringent cGMP conditions with comprehensive international certifications including ISO 9001, ISO 22000, HACCP, HALAL, GMPC, and U.S. GRAS recognition, our rCPB guarantees exceptional purity (>98% by HPLC), minimal protease contamination, and reliable performance in critical bioprocessing applications. The recombinant production method eliminates risks associated with animal-derived enzymes, ensuring superior safety profiles and compliance with evolving regulatory requirements for biopharmaceutical manufacturing. Each batch undergoes rigorous characterization including mass spectrometry, peptide mapping, and functional activity assays to verify structural integrity and biological performance.

The global insulin market continues to expand rapidly, driving increased demand for high-quality processing enzymes that can improve yields, reduce production costs, and ensure final product quality. Our rCPB is specifically optimized for the conversion of proinsulin to insulin, efficiently removing C-terminal basic residues with remarkable specificity and speed. Beyond insulin manufacturing, this versatile enzyme finds applications in protein sequencing, peptide mapping, and the production of various biotherapeutics requiring C-terminal modification. With flexible packaging options and comprehensive technical support, we provide pharmaceutical partners with the reliable enzyme solutions needed to advance their bioprocessing capabilities and maintain competitive advantage in global markets.
