Used in immunological research to quantify the expression levels of Toll-like Receptor 7 (TLR7) in human biological samples such as serum, plasma, cell lysates, and tissue homogenates. This ELISA kit enables researchers to study TLR7 involvement in innate immune responses, particularly in detecting viral single-stranded RNA and triggering downstream signaling pathways that lead to cytokine production. It is widely applied in studies related to autoimmune diseases, viral infections (such as influenza and HIV), and vaccine development. The kit supports high-throughput screening in drug discovery, especially for compounds modulating TLR7 activity, including agonists for antiviral therapies and antagonists for treating chronic inflammation or lupus. Its sensitivity and specificity make it a valuable tool for clinical research and biomarker validation.
