AI Technical Summary

Technical Problem

Existing humanized CEACAM5 antibodies exhibit poor expression characteristics in common mammalian expression systems, limiting their application as therapeutic agents.

Method used

A novel antibody has been developed, containing specific heavy and light chain variable region sequences, exhibiting good expression characteristics, binding affinity, and specificity. It is suitable for binding to CEACAM5 and can further bind to CD3 to form a multispecific antibody.

Benefits of technology

This study achieved good expression and efficient binding of the antibody to CEACAM5 in a mammalian expression system, reduced predicted immunogenicity, and improved therapeutic efficacy.
