Used in research settings to quantitatively measure levels of Insulin-like Growth Factor Binding Protein 3 (IGFBP-3) in biological samples such as serum, plasma, and cell culture supernatants. This kit supports studies related to growth disorders, metabolic diseases, and cancer, where IGFBP-3 plays a regulatory role in cell growth, apoptosis, and insulin-like growth factor (IGF) signaling. It is also employed in endocrine research to assess nutritional status, liver function, and growth hormone activity. The assay enables high-throughput, accurate detection, making it valuable for both clinical research and drug development.
