☑ Cell treatment (CT)

Western blot analysis of Phospho-HER2 / ErbB2 (Y1248) on different lysates with Rabbit anti-Phospho-HER2 / ErbB2 (Y1248) antibody (HA750926) at 1/1,000 dilution.

Lane 1: SK-Br-3 cell lysate
Lane 2: SK-Br-3 starved for 4 hours add 200ng/mL EGF for 15 minutes cell lysate
Lane 3: HeLa cell lysate
Lane 4: HeLa starved for 4 hours add 200ng/mL EGF for 15 minutes cell lysate

Observed band size: 180 kDa

Exposure time: 24 seconds;
4-20% SDS-PAGE gel.

Proteins were transferred to a PVDF membrane and blocked with 5% NFDM/TBST for 1 hour at room temperature. The primary antibody (HA750926) at 1/1,000 dilution was 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.

Immunocytochemistry analysis of HeLa cells starved for 4 hours add 200ng/mL EGF for 15 minutes labeling Phospho-HER2 / ErbB2 (Y1248) with Rabbit anti-Phospho-HER2 / ErbB2 (Y1248) antibody (HA750926) at 1/100 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-Phospho-HER2 / ErbB2 (Y1248) antibody (HA750926) at 1/100 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.
