Anti-ARPP-21 Antibody

Manufactured by Antibodies.com, this affinity-purified reagent is a rabbit polyclonal antibody directed against the Internal region of human ARPP-21 (also known as cAMP-regulated phosphoprotein 21, TARPP, or thymocyte cAMP-regulated phosphoprotein). It is supplied as a 50 µl liquid formulation in PBS containing 50% glycerol, 0.5% BSA and 0.02% sodium azide, at a working concentration of 1 mg/mL, and is unconjugated with an IgG isotype. The antibody selectively detects endogenous levels of the ARPP-21 protein and has been validated for use in Western blotting (WB), immunohistochemistry (IHC) and ELISA workflows across human and mouse samples. The polyclonal reagent is affinity-purified from rabbit antiserum by affinity-chromatography using an epitope-specific immunogen, helping to minimise off-target binding in sensitive applications. For laboratory handling, the vial is shipped at 4°C and should be aliquoted upon arrival and stored at -20°C, with repeated freeze/thaw cycles avoided to preserve antibody integrity. Intended strictly for research use, this primary antibody offers researchers a reliable tool for studying ARPP-21 expression and regulation in cell and tissue lysates, complementing ongoing investigations into cAMP-regulated neuronal phosphoproteins.
