Cell-Peptide Conjugate (CPC) Service

Peptides, as a new material that can both display protein functions and have a high degree of modularity in molecular design, have drawn great interest in the field of biomedicine. A large number of peptide products have been successfully commercialized over the past few decades. However, their functions are greatly limited by the following reasons: (i) their target binding affinity and selectivity are lower than proteins; (ii) easily digested by proteases in the biological environment; (iii) short circulating half-life.

Creative Biolabs is proud to announce the proprietary technology of a custom conjugation service for conjugates of synthetic peptides to cells for cell screening and in vivo studies.

Conjugation

"One-Step in Minutes"

Based on our CellFace™ conjugate technology platform, we utilize fucosyltransferases (Fuc T) to transfer Peptide to the surface of living cells in minutes. This one-step approach developed by scientist team is a fast, simple, and cost-effective technique for cell surface engineering. Using this method, any durg payload can be introduced to the cell surface without genetic modification of the host cells.
