Anti-RBP4 Antibody

Raised in rabbit and affinity-purified against a recombinant human RBP4 immunogen, this polyclonal antibody from Antibodies.com is offered as a 50 µL aliquot at a concentration of 1.0 mg/mL in an unconjugated format, ready for direct labelling or use in standard detection workflows. The reagent is validated for two core applications: Western blotting (WB) and immunohistochemistry (IHC), where it specifically recognises the endogenous total RBP4 protein in human and mouse samples. It is supplied in phosphate-buffered saline at pH 7.4 containing 150 mM sodium chloride, 0.02% sodium azide and 50% glycerol to preserve conformational stability during shipment on cold gel packs at 4 °C; on arrival, aliquots should be stored at −20 °C and protected from repeated freeze/thaw cycles. As a primary antibody intended for research use only, the polyclonal nature of the reagent provides multi-epitope coverage of retinol-binding protein 4, supporting consistent detection across the experimental conditions typically encountered when probing tissue lysates or fixed sections. The unconjugated presentation allows flexible pairing with HRP-, biotin- or fluorophore-based secondary reagents depending on the readout required, and the buffer formulation is compatible with most standard blocking and washing protocols used in immunoblotting and chromogenic IHC workflows.
