Catalogue number



Human Retinol Binding Protein, also known as RBP, is responsible for transporting and binding vitamin A. Human RBP has a binding site for 1 molecule of retinol and circulates in the plasma together with prealbumin as a protein complex. The prealbumin binding prevents greater glomerular losses of the human RBP. Only the retinol-free form of the RBP, which has no affinity for prealbumin, undergoes glomerular filtration unhindered as a result of its low Mw. Human RBP is re-absorbed by the tubular cells and catabolized there.


Human Retinol Binding Protein Native produced in urine from the patients with renal tubular proteinuria having a molecular mass of approximately 21kD.


Urine from the patients with renal tubular proteinuria.
