Used in biomedical research to measure insulin-like growth factor binding protein 1 (IGFBP-1) levels in biological samples such as serum, plasma, or cell culture supernatants. It is commonly applied in studies related to fetal development, intrauterine growth restriction, and preeclampsia, as IGFBP-1 plays a key role in regulating insulin-like growth factors during pregnancy. The kit enables researchers to quantify IGFBP-1 with high sensitivity and specificity using the ELISA method, supporting investigations in reproductive health, metabolic disorders, and liver function. Widely used in academic, clinical, and pharmaceutical research settings to understand hormonal regulation and assess biomarkers in various disease models.
