Used in biomedical research to quantitatively measure fibroblast growth factor receptor 1 (FGFR1) levels in rat tissue extracts, cell lysates, or biological fluids. This ELISA kit is particularly useful in studies related to cell proliferation, tissue repair, angiogenesis, and developmental biology. It enables researchers to monitor FGFR1 expression changes in response to disease conditions such as cancer, fibrosis, or metabolic disorders, as well as in preclinical evaluation of targeted therapies. The assay provides high specificity and sensitivity, making it suitable for both academic and pharmaceutical research settings.
