Validation Data Gallery

Filter:
  • Western Blot (WB) analysis of HEK-293 cells using Phospho-PERK/EIF2AK3 (Thr982) Recombinant antibody (82534-1-RR)

    WB analysis of HEK-293 using 82534-1-RR (same clone as 82534-1-PBS)

    Non-treated HEK-293 cells and Calyculin A treated HEK-293 cells were subjected to SDS PAGE followed by western blot with 82534-1-RR (Phospho-PERK/EIF2AK3 (Thr982) antibody) at dilution of 1:5000 incubated at room temperature for 1.5 hours. The membrane was stripped and re-blotted with beta actin antibody (66009-1-Ig) as loading control. This data was developed using the same antibody clone with 82534-1-PBS in a different storage buffer formulation.

  • Western Blot (WB) analysis of various lysates using Phospho-PERK/EIF2AK3 (Thr982) Recombinant antibody (82534-1-RR)

    WB analysis using 82534-1-RR (same clone as 82534-1-PBS)

    Non-treated NIH/3T3 cells and Calyculin A treated NIH/3T3 cells were subjected to SDS PAGE followed by western blot with 82534-1-RR (Phospho-PERK/EIF2AK3 (Thr982) antibody) at dilution of 1:2500 incubated at room temperature for 1.5 hours. This data was developed using the same antibody clone with 82534-1-PBS in a different storage buffer formulation.

Background Information

EIF2AK3 encodes the protein kinase RNA-like ER kinase (PERK), a key regulator of the unfolded protein response (UPR) in response to ER stress. Under ER stress conditions, activation of PERK is triggered by the dissociation of glucose-regulated protein (GRP) 78 (also known as BiP) from its luminal domain, followed by oligomerization and autophosphorylation. Phosphorylated PERK subsequently phosphorylates eukaryotic translation initiation factor 2 alpha (eif2α), to attenuate global protein translation and reduce incoming ER protein load via upregulated ER chaperone expression.
