Anti-PKR Antibody

Raised in rabbit against the PKR (EIF2AK2) target, this polyclonal antibody is supplied by Antibodies.com as an unconjugated, 100 µl aliquot used in western blot, immunohistochemistry, and ELISA workflows with human samples. PKR is the interferon-induced, double-stranded RNA-activated protein kinase that phosphorylates eukaryotic translation initiation factor 2-alpha, coupling viral detection to translational control, apoptotic signaling, and integrated stress responses. Investigators studying antiviral innate immunity, virus-host interactions, and the cellular response to cytoplasmic dsRNA probe PKR expression and activation state through these assays. The unconjugated format allows direct conjugation to a preferred reporter or pairing with secondary antibodies matched to the rabbit host, and the polyclonal profile increases recognition across multiple PKR epitopes, including post-translationally modified or alternatively processed forms. Handling guidance supplied with the vial should be followed to preserve activity across freeze-thaw cycles, and the reagent is intended for research use only.
