Anti-DBP Antibody

Vitamin D-binding protein (DBP), also called group-specific component (GC), is the major plasma carrier of vitamin D metabolites and is implicated in actin scavenging, fatty acid transport, and immune modulation. This unconjugated rabbit polyclonal reagent from Antibodies.com is supplied at 1 mg/ml in PBS with 0.1% sodium azide and 50% glycerol as a 100 µl aliquot, ready for use in western blot, immunohistochemistry, and immunofluorescence workflows. The antibody was raised in rabbit and shows reactivity with human, mouse, and rat samples, supporting translational studies that compare DBP expression across species and tissue types. Researchers commonly deploy it to track DBP in hepatic tissue, kidney sections, and cultured cell lines, where it can reveal changes linked to vitamin D status, liver disease, and certain inflammatory conditions. The polyclonal format offers broader epitope coverage than a monoclonal reagent, which is helpful when probing a circulating protein that exists in multiple isoforms. For best results, store aliquots frozen and protect from light to preserve the glycerol-stabilized solution across freeze-thaw cycles.
