KMD Bioscience is experienced in monoclonal antibody production. Supported by skilled scientists and a mature antibody production platform, we can provide you with high-quality monoclonal antibody production service. With many years of experience in phage display technology projects, KMD Bioscience has successfully produced bovine monoclonal antibodies, especially those with ultralong CDR3 (Complementarity Determining Region 3).
Bovine (Cow/ Cattle) can produce antibodies with an ultralong CDR3 loop and a few variable regions in antibody-related studies. Under natural conditions, approximately 10% of bovine antibodies contain this ultralong CDR3 structural domain, which forms a knot-like shape and primarily mediates the affinity of the antibody for the antigen, giving it a higher antigen binding capacity. To overcome the conformational entropy loss mechanism associated with long loops, bovines use disulfide bonds to anchor the extra-long CDR3 structural domain.
The bovine monoclonal antibody produced by KMD Bioscience has a high Immunologic affinity. Related testing services are available and the quantity supplied is guaranteed to meet your experimental requirements. KMD Bioscience has a mature antibody production platform that can provide one-stop antibody services, including antibody humanization, antibody sequencing, antibody purification, antibody labeling, and other antibody services.
Bovine Monoclonal Antibody Production Service Background
Bovine monoclonal antibodies have unique advantages in the study of antigen structure. The ultralong CDR3 loop of the bovine antibody is the longest of any other species (50-61 amino acids) and facilitates the recognition of deep-seated epitopes. Structural and deep sequencing analysis shows that the CDR3 ultralong loop contains an even number of cysteines, forming a specific structure in which the cysteines are involved in the formation of a diverse disulfide-bonded “knob” domain supported by a β-chain “stalk”. This ultralong CDR3 loop allows bovine antibodies to more effectively attack a wide range of bacteria and viruses or to capture molecular targets, particularly antigens that are not recognized by conventional antibodies, such as GPCRs. KMD Bioscience provides greater access to bovine monoclonal antibodies with high purity and high specificity using proprietary protocols.
KMD Bioscience offers bovine monoclonal antibody production services based on phage display technology. Customized services are available to meet your needs, including peptide antigen design and protein antigen production.
