KMD Bioscience has dedicated years to antibody preparation research. Our company possesses professional technicians with extensive experience in antibody preparation, enabling us to offer custom services including polyclonal and monoclonal antibodies. Polyclonal antibodies (pAbs) are a collection of immunoglobulins produced by multiple B lymphocytes, found in the serum of immunized animals and obtained by immunizing a host with an antigen. Compared to monoclonal antibodies (mAbs), pAbs recognize multiple epitopes on the same antigen, offering superior affinity and faster binding kinetics. Their advantages, such as the ability to cause agglutination and precipitation reactions, make them widely applicable in immunological diagnostics. KMD Bioscience is committed to providing high-quality Antibody Production Services. We have established a mature and comprehensive Antibody Preparation Platform, offering pAb services for diverse species including bovine, murine, ovine, and rabbit.

Bovine antibodies possess unique characteristics. Approximately 10% of bovine pAbs feature an exceptionally long "loop" within the CDR3 domain. This loop forms a knob-shaped structure primarily mediating the antibody's affinity for the antigen, conferring higher antigen-binding capability. We are dedicated to providing clients with high-immunoreactivity bovine pAbs and related testing services. Validation using various techniques like ELISA, Western Blot, and IHC is available, ensuring the preparation of highly sensitive antibodies, guaranteed delivery quantities, and fulfillment of experimental needs. Within our completed pAb projects, we have successfully generated bovine pAbs exhibiting neutralizing titers exceeding 1:800,000,000.
