Anti-PEK / PERK (Ab-981) Antibody

Manufactured by Antibodies.com, this affinity-purified rabbit polyclonal reagent is raised against a synthetic non-phosphopeptide derived from human PEK / PERK around the threonine 981 phosphorylation site, enabling selective detection of total endogenous PEK / PERK protein. Supplied at 1.0 mg/mL in PBS (pH 7.4) with 150 mM NaCl, 0.02% sodium azide and 50% glycerol, the 50 µl size is unconjugated and validated for ELISA, Western blot, immunocytochemistry/immunofluorescence and immunohistochemistry workflows. The antibody is reactive with human, mouse and rat samples, providing flexibility across common model systems. For best stability it should be stored at -20°C upon receipt and protected from repeated freeze/thaw cycles. Intended strictly for research use, this lot is a dependable choice for laboratories probing unfolded-protein-response signalling through the PEK/PERK kinase.
