Gene Information

human ... RBP2(5948)

General description

The gene RBP2 (retinol-binding protein 2) is mapped to human chromosome 3q23. It is mainly expressed in the small intestine and is a cytosolic protein. . It belongs to the CRBP (cellular retinoic-acid-binding protein) intracellular lipid-binding protein family.

Immunogen

retinol binding protein 2, cellular recombinant protein epitope signature tag (PrEST)

Application

Anti-RBP2 antibody produced in rabbit has been used in Western Blotting and immunocytochemistry.

Biochem/physiol Actions

RBP2 (retinol-binding protein 2) is responsible for vitamin A absorption/uptake. It works as a cellular retinoid chaperone. RBP2 associates with retinol and retinal, thereby assisting in retinoid homeostasis.

Features and Benefits

Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:
  • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
  • Protein array of 364 human recombinant protein fragments.

Linkage

Corresponding Antigen APREST79303

Physical form

Solution in phosphate buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide.
