Immunocytochemistry analysis of Jurkat cells labeling ERK1/2 with Rabbit anti-ERK1/2 antibody (ET1601-29) at 1/2,000 dilution and competitor's antibody at 1/1,600 dilution. Cells were fixed in 4% paraformaldehyde for 20 minutes at room temperature, permeabilized with 0.1% Triton X-100 in PBS for 5 minutes at room temperature, then blocked with 1% BSA in 10% negative goat serum for 1 hour at room temperature. Cells were then incubated with Rabbit anti-ERK1/2 antibody (ET1601-29) at 1/2,000 dilution and competitor's antibody at 1/1,600 dilution in 1% BSA in PBST overnight at 4 ℃. Goat Anti-Rabbit IgG H&L (iFluor™ 488, HA1121) was used as the secondary antibody at 1/1,000 dilution. PBS instead of the primary antibody was used as the secondary antibody only control. Nuclear DNA was labelled in blue with DAPI. Beta tubulin (M1305-2, red) was stained at 1/100 dilution overnight at +4℃. Goat Anti-Mouse IgG H&L (iFluor™ 594, HA1126) was used as the secondary antibody at 1/1,000 dilution.

Western blot analysis of ERK1/2 on different lysates with Rabbit anti-ERK1/2 antibody (ET1601-29) at 1/2,000 dilution. Lane 1: HEK-293-si NT cell lysate Lane 2: HEK-293-si ERK1/2 cell lysate Lysates/proteins at 10 µg/Lane. Predicted band size: 41/43 kDa Observed band size: 41/43kDa Exposure time: 20 seconds; 4-20% SDS-PAGE gel. ET1601-29 was shown to specifically react with ERK1/2 in HEK-293-si NT cells. Weakened band was observed when HEK-293-si ERK1/2 sample was tested. Hela-si NT and HEK-293-si ERK1/2 samples were subjected to SDS-PAGE. Proteins were transferred to a PVDF membrane and blocked with 5% NFDM in TBST for 1 hour at room temperature. The primary antibody (ET1601-29, 1/2,000) and Loading control antibody (Rabbit anti-GAPDH, ET1601-4, 1/10,000) were used in 5% NFDM/TBST at 4℃ overnight. Goat Anti-rabbit IgG-HRP Secondary Antibody (HA1001) at 1:50,000 dilution was used for 1 hour at room temperature.
