Mouse anti Human retinol binding protein 4 antibody recognizes human serum retinol binding protein 4 (RBP4), a 201 amino acid 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 by filtration through the kidney glomeruli. Defects in RBP4 are a cause of retinol-binding protein deficiency and can cause night vision problems (Besch et al. 2003). RBP4 gene variants have been implicated in insulin resistance (Saucedo et al. 2014)

Mouse anti Human retinol binding protein 4 antibody recognizes free RBP4 and RBP4 in complex with transthyretin. It reacts with apo- as well as holo-RBP4. Mouse anti Human RBP4 antibody recognizes RBP4 as a single band of ~20 kDa in HepG2 cell line whole cell lysates by western blotting under reducing conditions.

Instructions For Use
Please refer to the PrecisionAb western blotting protocol. For additional information on secondary antibody dilution and exposure time see product web page.

Positive Control Lysate

Lysate Composition
400μg HepG2 lysate lyophilized in RIPA buffer.
Lysate Reconstitution
- If using DDT reconstitute the lyophilized lysate with 190μl DI H2O, add 200μl 2x Laemmli Sample Buffer and 10μl 2M DTT.
- If using BME reconstitute the lyophilized lysate with 180μl DI H2O, add 200μl 2x Laemmli Sample Buffer and 20μl BME.
Heat at 95°C for 5 minutes. For 10 well mini gels load 25μl. For other gel and comb formats please refer to the PrecisionAb western blotting protocol.
