WB
Western blot analysis of Bak on different lysates with Rabbit anti-Bak antibody at 1/1,000 dilution.
Lane 1: HeLa cell lysate
Lane 2: AGS cell lysate
Lane 3: HEK-293 cell lysate
Lysates/proteins at 10 µg/Lane.
Exposure time: 3 minutes;
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 at 1/1,000 dilution was used in 5% NFDM/TBST at 4℃ overnight. Goat Anti-Rabbit IgG - HRP Secondary Antibody at 1/50,000 dilution was used for 1 hour at room temperature.
IHC
Immunohistochemical analysis of paraffin-embedded human colon tissue with Rabbit anti-Bak antibody at 1/1,000 dilution.
The section was pre-treated using heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0) for 20 minutes. The tissues were blocked in 1% BSA for 20 minutes at room temperature, washed with ddH2O and PBS, and then probed with the primary antibody at 1/1,000 dilution for 1 hour at room temperature. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.
IP
Bak was immunoprecipitated from 0.2 mg HeLa cell lysate with Rabbit anti-Bak antibody at 2µg/25 µl agarose. Western blot was performed from the immunoprecipitate usingRabbit anti-Bak antibody at 1/1,000 dilution. Anti-Rabbit IgG for IP Nano-secondary antibody at 1/5,000 dilution was used for 1 hour at room temperature.

Lane 3: Rabbit IgG instead of Rabbit anti-Bak antibody in HeLa cell lysate
Blocking/Dilution buffer: 5% NFDM/TBST
