Adenosine triphosphate-binding cassette subfamily B, member 4, also called MDR3, is a protein that in humans is encoded by the ABCB4 gene. The membrane-associated protein encoded by this gene is a member of the superfamily of ATP-binding cassette (ABC) transporters. ABCB4 mutations represent a genetic factor involved in this peculiar form of cholesterol gallstone disease in adults.

Variations in secondary/substrate sensitivities and test protocols may require the ABCB4 antibody to be titrated for optimal performance.

Human partial recombinant protein (AA 601-720) was used as the immunogen for this ABCB4 antibody.

The lyophilized ABCB4 antibody can be stored at 4oC to -20oC.After reconstitution, aliquot and store at -20oC.Avoid repeated freeze/thaws.
