Used in biomedical research to quantify levels of human Tyrosine Kinase A (TrkA) in biological samples such as serum, plasma, cell lysates, and tissue homogenates. This ELISA kit enables researchers to study TrkA expression in neurological disorders, cancer, and inflammatory diseases where TrkA signaling plays a role. It is particularly valuable in studies related to nerve growth factor (NGF) pathways, pain mechanisms, neurodegeneration, and tumor progression. The assay provides high sensitivity and specificity, allowing for accurate measurement of TrkA protein concentrations in small sample volumes, supporting both basic research and drug development efforts targeting the TrkA receptor.
