Anti-RBP4 Antibody

This polyclonal reagent from Antibodies.com targets retinol-binding protein 4 (RBP4), the specific serum carrier that delivers all-trans retinol from hepatic stores to peripheral tissues. Raised in rabbit hosts and supplied at 1 mg/ml in PBS with 0.1% sodium azide and 50% glycerol, the antibody is unconjugated and validated for Western blot and immunohistochemistry workflows on human, mouse, and rat samples. Investigators studying type 2 diabetes, obesity, insulin resistance, and age-related macular degeneration use RBP4 detection to follow retinoid transport dysregulation, with adipose-secreted RBP4 routinely profiled as a candidate biomarker of metabolic syndrome. The 100 µl vial is shipped refrigerated; store at 4 °C, aliquot to limit freeze-thaw cycles, and protect from light to preserve activity. Polyclonal reactivity broadens epitope coverage compared with monoclonal alternatives, supporting consistent signal in formalin-fixed paraffin-embedded sections, retinal tissue preparations, and membrane-enriched protein fractions.
