Anti-PKR Antibody

Offered through Antibodies.com, this Rabbit polyclonal antibody targets PKR (Protein Kinase R) and is supplied in a 50 µL liquid format at a concentration of 1 mg/mL. The reagent was affinity-purified from rabbit antiserum by affinity-chromatography using an epitope-specific immunogen derived from a synthesized peptide around the non-phosphorylation site of T446 in human PKR, and it detects endogenous levels of the PKR protein. It is unconjugated and formulated in PBS containing 50% glycerol, 0.5% BSA, and 0.02% sodium azide, and it is intended for research use only. The antibody has been validated for Western blotting (WB), immunohistochemistry (IHC), and ELISA applications, and the manufacturer reports reactivity with Human, Mouse, and Rat samples. For shipping and storage, the vial is shipped at 4 °C; upon receipt it should be aliquoted and stored at −20 °C, with repeated freeze/thaw cycles avoided to preserve reagent integrity. This polyclonal reagent is suited to laboratories investigating interferon-induced antiviral signalling, translational control, and stress-response pathways where PKR plays a regulatory role.
