Anti-FGF23 Antibody

This rabbit polyclonal reagent from Antibodies.com targets FGF23, the bone-derived hormone that governs phosphate homeostasis and vitamin D activation through action on renal tubules. Raised against the human FGF23 protein, the antibody enables detection of endogenous FGF23 expression in human tissue samples and is validated for western blot and immunohistochemistry workflows.

Supplied as 100 µL of a 1 mg/mL stock in PBS buffer containing 0.1% sodium azide and 50% glycerol, the product is ready for dilution into standard immunoblotting and immunostaining protocols. Polyclonal rabbit immunoglobulins recognize multiple epitopes on the FGF23 molecule, supporting consistent visualization across bone, kidney, and tumor tissue specimens where FGF23 dysregulation is being investigated.

Researchers studying X-linked hypophosphatemic rickets, tumor-induced osteomalacia, and chronic kidney disease-mineral bone disorder commonly use this antibody to characterize osteocyte and osteoblast FGF23 production in vivo. The unconjugated format lets users pair the reagent with any species-compatible secondary reporter or fluorescent label suited to a given assay design.
