Anti-P4HA3 Antibody

This rabbit polyclonal IgG from Antibodies.com is supplied as a 100 µl vial of unconjugated reagent raised against human prolyl 4-hydroxylase subunit alpha 3 (P4HA3). P4HA3 encodes one of the catalytic alpha subunits of prolyl 4-hydroxylase, the enzyme complex that hydroxylates proline residues in procollagen and contributes to oxygen sensing through HIF-alpha hydroxylation. The reagent is validated for western blot detection of endogenous P4HA3 in human samples, supporting work on collagen biosynthesis, extracellular matrix remodeling, and hypoxia pathway research. Host species is rabbit, clonality is polyclonal, isotype is IgG, and the conjugate is unconjugated, giving laboratories flexibility in secondary antibody selection and downstream detection chemistry. For best stability, the vial should be kept refrigerated in working aliquots to limit freeze-thaw cycles; handle on ice during western blot protocols and dilute into appropriate blocking buffer before use.
