Rat Retinol Binding Protein 4, Plasma (RBP4) ELISA Kit

This rat-specific quantitative immunoassay from Assay Genie measures Retinol Binding Protein 4 (RBP4), a 21 kDa plasma carrier for vitamin A linked to obesity, insulin resistance, type 2 diabetes, and renal dysfunction in rodent models. The kit quantifies circulating RBP4 concentrations across metabolism, endocrinology, and nephrology research workflows.

Compatible with plasma samples, serum specimens, tissue homogenates, cell lysates, and cell culture supernatants, the assay accommodates standard laboratory sample preparations. The 96-assay format enables mid-throughput screening of rodent cohorts, while the absorbance-based colorimetric method allows quantification on standard microplate readers.

Each kit includes pre-coated microplate wells, calibrated reference standards, detection antibody, substrate, and assay buffers sufficient to complete the full plate. Researchers studying hepatic retinoid handling, adipose-derived adipokine signaling, or diabetic rodent phenotypes can integrate the assay into longitudinal protocols examining circulating RBP4 and its correlation with metabolic endpoints.
