Anti-CSNK2A2 Antibody

Validated for Western blot and immunohistochemistry across human, mouse, and rat samples, this unconjugated rabbit polyclonal reagent from Antibodies.com targets CSNK2A2, the catalytic alpha' subunit of casein kinase II. CSNK2A2 partners with regulatory beta subunits to assemble the tetrameric CK2 holoenzyme, a constitutively active serine/threonine kinase implicated in transcription, cell cycle progression, Wnt signaling, and apoptosis regulation.

Supplied as 100 µl of polyclonal antiserum in a vial, the antibody supports multiple rounds of membrane probing and tissue section staining. The alpha' isoform shows a more tissue-restricted distribution than its CSNK2A1 paralog, making this reagent useful for kinase isoform expression studies, tumor biology research, and investigations into substrate phosphorylation networks. Store refrigerated; aliquot and freeze for longer-term use.
