Human RBP-4 PharmaGenie ELISA Kit (SBRS0118)

The Human RBP-4 ELISA kit from Assay Genie is a competitive immunoassay that quantifies Retinol-Binding Protein 4, a 21 kDa circulating lipocalin-family protein that carries retinol (vitamin A) from hepatic stores to peripheral tissues. RBP-4 is secreted primarily by hepatocytes and adipocytes, and it is an active target of investigation in metabolic disease, insulin resistance, type 2 diabetes, obesity, and cardiovascular research. Circulating RBP-4 concentrations have been evaluated as a biomarker for metabolic syndrome and related conditions, as well as for monitoring responses in nutritional intervention studies.

The kit supports quantitative analysis of cell culture supernatants and serum samples in a 96 assays format. Each plate includes pre-coated wells, assay buffer, detection reagents, and a standard curve for analyte interpolation. Investigators working in adipokine biology, hepatic function studies, and nutritional biomarker development commonly employ this assay in screening workflows and biopharma research applications.

Storage recommendations include keeping kit components refrigerated and protected from light until use. Reconstituted standards should be aliquoted and frozen to minimize freeze-thaw cycles and preserve binding activity. All reagents are intended for research use only and are not cleared for diagnostic procedures.
