RBP4 delivers retinol from the liver to the peripheral tissues. In plasma, the rbp-retinol complex interacts with transthyretin, this prevents its loss by filtration through the kidney glomeruli.
RBP-4 Human Recombinant produced in E.Coli is single, a non-glycosylated, Polypeptide chain containing 183 amino acids fragment (19-201) corresponding to the mature Retinol Binding Protein, having a total molecular mass of 25.57kDa and fused with a 4.5kDa amino-terminal hexahistidine tag.
The RBP4 is purified by proprietary chromatographic techniques.
Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time.
Avoid multiple freeze-thaw cycles.
Greater than 95.0% as determined by SDS-PAGE.
