Used in biomedical research to measure retinol-binding protein 4 (RBP-4) levels in mouse samples, this ELISA kit helps investigate metabolic disorders such as insulin resistance, obesity, and type 2 diabetes. It enables researchers to assess RBP-4 as a potential biomarker in serum, plasma, or tissue extracts. The kit is widely applied in studies exploring the link between vitamin A metabolism and metabolic syndrome, as well as in preclinical evaluations of therapeutic interventions targeting adipokine signaling. Its high sensitivity and specificity make it suitable for quantifying low concentrations of RBP-4 in small sample volumes, supporting reproducible and accurate data in experimental models.
