General Notes
Mouse anti Human Retinol Binding Protein 4 antibody, clone RB42 recognizes human serum Retinol Binding Protein 4 (RBP4), a single-chain glycoprotein belonging to the lipocalin family, which is responsible for the transport of Retinol (vitamin A1) from the liver to peripheral target tissues. In plasma, the RBP4-retinol complex interacts with transthyretin preventing its loss through filtration through the kidney glomeruli. Defects in RBP4 are a cause of retinol-binding protein deficiency and can cause night vision problems. RBP4 has been described as an adipokine that contributes to insulin resistance in mice. Mouse anti Human Retinol Binding Protein 4 antibody, clone RB42 recognizes free RBP4 and RBP4 in complex with transthyretin. It reacts with apo- as well as holo-RBP4. It recognizes human RBP4 in western blotting under reducing conditions.
