Anti-CSNK2B Antibody

Primary Antibodies from Antibodies.com include this rabbit polyclonal reagent raised against the regulatory β subunit of casein kinase II (CSNK2B, also called CK2β). Supplied as 50 µl of unconjugated IgG in a single vial, the antibody is validated for Western blot and immunohistochemistry on human, mouse, and rat samples. CSNK2B assembles with the catalytic CK2α/α′ subunits into a tetrameric holoenzyme that phosphorylates hundreds of substrates and tunes Wnt, NF-κB, and PI3K signaling, making a robust polyclonal reagent against this regulatory partner valuable for probing kinase complex distribution in tissue sections and confirming expression in cell lysates. Polyclonal reactivity from a rabbit host gives broader epitope coverage than a monoclonal, and the IgG isotype pairs readily with common HRP- or fluorophore-conjugated secondaries for chromogenic or fluorescent detection. Short-term storage at -20 °C in single-use aliquots preserves activity across repeated experiments. Researchers mapping CK2 subunit stoichiometry, signalosome composition, or downstream substrate regulation can rely on this Antibodies.com reagent to visualize CSNK2B across diverse experimental contexts.
