  • other_names：  
  • ADRB2; E2AK2; EIF2AK2; EIF2aK; PRKR
  • Purification：  
  • Antibodies were produced by immunizing rabbits with synthetic peptide and KLH conjugates. Antibodies were purified by affinity-chromatography using epitope-specific peptide.
  • Specificity：  
  • The antibody detects endogenous level of total PKR protein.
  • Applications：  
  • WB IHC IF
  • Background：  
  • Following activation by double-stranded RNA in the presence of ATP, the kinase becomes autophosphorylated and can catalyze the phosphorylation of the translation initiation factor EIF2S1, which leads to an inhibition of the initiation of protein synthesis. Double-stranded RNA is generated during the course of a viral infection.
