Research context & evidence
Target information is kept separate from product-level validation so you can review the biology and the reagent evidence independently.
Retinol binding protein 4 (RBP4) is a secreted lipocalin that transports retinol from hepatic stores to peripheral tissues. In circulation, retinol-bound RBP4 can associate with transthyretin, which reduces renal filtration of the complex, while cellular uptake and retinoid delivery support vitamin A-dependent physiology.
Retinol binding protein 4 (RBP4) is commonly studied in vitamin A and retinoid transport, liver-adipose metabolic biology and circulating biomarker research. Use the catalogue filters below to review ABMIUM products associated with RBP4, then confirm species, sample type, assay format, application and product-level validation before use.
