KMD Bioscience has long been dedicated to antibody development research, with an experienced technical team, mature and stable process systems, and comprehensive antibody production facilities. We offer recombinant monoclonal antibody (mAb) generation services from multiple species, including mouse, rabbit, alpaca, bovine, sheep, and chicken.
Despite possessing a limited number of antibody variable‑region genes, bovines have evolved to expand their antigen‑recognition repertoire through the encoding of ultra‑long complementarity‑determining region 3 (CDR3) domains. Approximately 10% of circulating bovine antibodies carry such ultra‑long CDR3 sequences, which fold into a characteristic knob‑like structure that serves as the core epitope‑binding site, conferring enhanced antigen‑binding capacity. To minimize the conformational entropy penalty associated with the ultra-long CDR3 loop during antigen engagement, bovine antibodies utilize conserved intra‑chain disulfide bonds to stabilize this structural domain, thereby maintaining both high binding activity and molecular stability. Leveraging our well‑established single B cell antibody screening platform, KMD Bioscience is capable of generating bovine monoclonal antibodies with high antigen‑binding affinity. In addition, our comprehensive quality control and testing systems ensure that the yield and quality metrics of the delivered antibodies fully meet the specific requirements of your experimental applications.
