A polyclonal antibody for detection of PKR phospho Thr258) from Human. This PKR phospho Thr258) antibody is for WB, IHC-P, ELISA. It is affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogenand is unconjugated. The antibody is produced in rabbit by using as an immunogen synthesized peptide derived from human PKR around the phosphorylation site of T258
