Used in veterinary immunology research to detect and quantify dog leukocyte antigens (DLA) associated with the major histocompatibility complex (MHC). Helps in studying immune responses, organ transplant compatibility, autoimmune diseases, and genetic predisposition to certain illnesses in canines. Commonly applied in breeding programs to assess DLA matching and reduce the risk of inherited immune disorders. Also supports vaccine development and monitoring of immune system activity in clinical trials.
