Anti-RAB22A Antibody

This rabbit polyclonal reagent targets RAB22A, a member of the Ras-related small GTPase superfamily that localizes to early and late endosomal compartments and supports vesicular trafficking between endosomes and the plasma membrane. Produced by Antibodies.com and validated for Western blot (WB) and immunohistochemistry (IHC) workflows, the antibody is supplied as 100 µl of unconjugated antiserum, ready for downstream conjugation with HRP, biotin, or fluorophore reporters as required. Species reactivity data confirm detection of endogenous RAB22A in human and mouse samples, supporting use in cell lysates and fixed tissue sections from both organisms. The polyclonal format offers recognition of multiple epitopes across the RAB22A primary sequence, helping maintain signal across heterogeneous expression levels and in partially degraded lysate preparations. Working dilutions should be determined empirically against a positive control lysate; the unconjugated format lets laboratories pair the reagent with species-matched secondary antibodies already in their workflow. For routine handling, store refrigerated and protect from light where applicable, and aliquot upon receipt if extended storage is anticipated to minimize repeated freeze-thaw exposure of the polyclonal titer.
