eIF2a phosphorylation
WT and PKR-KO A549 cells were seeded at a density 5 10e5 cells/well of in six-well plates. After 16
hr the cells were transfected with 1 ug/ml pIC using Lipofectamine 2000 and incubated for 2 hr. The
cells were harvested in NP-40 lysis buffer as above. The lysates were centrifuged at 1000Xg for 12
min at 4°C. The total protein amounts in the cleared supernatants were determined by the Bradford
method (Bio-Rad), and 30 ug of total protein was separated on 12% SDS-PAGE, transferred onto
polyvinylidene difluoride(PVDF)membranes (0.45 um) (BioRad), and probed with either antibody
against total anti-eIF2a or Ser-51-phosphorylated eIF2a(Cell signaling Technology).
