Know who made it. See the evidence. Buy through one marketplace.
Retinol-binding protein that mediates retinol transport in blood plasma (PubMed: 5541771). Delivers retinol from the liver stores to the peripheral tissues (Probable). Transfers the bound all-trans retinol to STRA6, that then facilitates retinol transport across the cell membrane (PubMed: 22665496).
Fully tested in-house by ABMIUM, or supported by an advanced validation report from a partner reviewed by ABMIUM. Highest confidence. Non-conformities fully supported under the ABMIUM Product Promise.
Quality verified. Independent collaborator or expected-performance data available. Product meets ABMIUM quality standards.
Expected to work based on structural and biochemical data. Not yet directly tested by ABMIUM or a collaborator. No non-conformity support for this combination.
Not recommended for this application or species/sample combination. This may indicate either evidence of unsuitability or that the combination has not been tested and therefore cannot currently be recommended.

Retinol binding protein 4 (RBP4), also written retinol-binding protein 4, is the principal circulating carrier of retinol (vitamin A). ABMIUM catalogue products linked below support research on RBP4 biology.
Biological function: 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.
