Used in biomedical research to quantify Insulin-like Growth Factor Binding Protein 4 (IGFBP-4) levels in rat biological samples such as serum, plasma, and tissue homogenates. This kit supports studies related to growth regulation, metabolic disorders, and endocrine function in rodent models. It is particularly valuable in research involving insulin-like growth factor signaling pathways, cell proliferation, and apoptosis. The assay enables high-throughput, accurate measurement of IGFBP-4, aiding in the investigation of diseases like diabetes, cancer, and developmental abnormalities in preclinical studies.
