• 
  Western blot analysis of ERK1 expression in A431 (A), NIH3T3 (B), PC12 (C) whole cell lysates. (Predicted band size: 43 kD; Observed band size: 44 kD)
• 
  Immunofluorescent analysis of ERK1 staining in A431 cells. Formalin-fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 5-10 minutes and blocked with 3% BSA-PBS for 30 minutes at room temperature. Cells were probed with the primary antibody in 3% BSA-PBS and incubated overnight at 4 °C in a humidified chamber. Cells were washed with PBST and incubated with a DyLight 594-conjugated secondary antibody (red) in PBS at room temperature in the dark. DAPI was used to stain the cell nuclei (blue).
