Used in biomedical research to detect and quantify secreted frizzled-related protein 2 (sFRP-2) in rat biological samples such as serum, plasma, or tissue homogenates. This ELISA kit is particularly valuable in studies related to Wnt signaling pathway regulation, which plays a key role in tissue development, cell proliferation, and cancer progression. Researchers use it to investigate cardiovascular diseases, fibrosis, and tissue repair mechanisms in rat models. The assay enables high sensitivity and specificity, allowing accurate measurement of sFRP-2 levels in experimental conditions, supporting both basic science and preclinical research.
