Human Anti-CD22 Recombinant Antibody (clone g5/44); scFv Fragment (CAT#: FAMAB-0047-YC-S(P))
Murine mAb m5/44 was humanized by CDR grafting to create g5/44. The clone g5/44 bind CD22 with subnanomolar affinity. Based on shown results, a calicheamicin conjugate of g5/44, CMC-544, was selected for further development as a targeted chemotherapeutic agent for the treatment of B-cell malignancies.
We specialize in custom recombinant antibody production, offering seamless execution from provided sequences to high-quality antibody deliverables, ensuring optimal yield and purity.
