Used in research settings to measure levels of unphosphorylated insulin-like growth factor binding protein-1 (IGFBP-1) in biological samples such as serum, plasma, or cell culture supernatants. This ELISA kit enables scientists to study the role of IGFBP-1 in metabolic regulation, fetal development, and insulin signaling pathways. It is particularly useful in studies related to diabetes, pregnancy complications like intrauterine growth restriction, and conditions involving insulin resistance. The assay provides a quantitative measurement, supporting reproducible and sensitive detection essential for clinical and experimental investigations.
