Used in immunological research to quantify human Toll-like receptor 2 (TLR2) levels in biological samples such as serum, plasma, or cell culture supernatants. Enables researchers to study TLR2 involvement in innate immune responses, inflammation, and host-pathogen interactions. Commonly applied in studies related to infectious diseases, autoimmune disorders, and vaccine development. Provides a reliable, sensitive, and high-throughput method for detecting TLR2 protein expression under various experimental conditions.
