Used in biomedical research to detect and quantify Human Curly Homolog 9 (FZD9) protein levels in cell lysates, tissue extracts, and biological fluids. This ELISA kit is particularly useful in studying Wnt signaling pathways, which play critical roles in embryonic development, cell proliferation, and cancer progression. Researchers apply this kit in neuroscience and oncology studies where FZD9 expression is linked to synaptic function, neurodevelopmental disorders, and certain cancers such as small cell lung cancer. The assay enables high sensitivity and specificity, supporting reliable data collection in both basic research and drug development settings.
