Used in immunological research to quantify levels of Toll-like receptor 4 (TLR4) in pig samples, this ELISA kit enables scientists to study innate immune responses, particularly in relation to pathogen recognition and inflammation. It is widely applied in veterinary research, vaccine development, and disease monitoring, especially in swine health studies involving bacterial infections like those caused by Gram-negative bacteria. The kit supports the investigation of immune modulation and helps evaluate the efficacy of therapeutic agents in preclinical pig models.
