WB
Western blot analysis of Histone H3 (acetyl K36) on different lysates with Rabbit anti-Histone H3 (acetyl K36) antibody at 1/1,000 dilution.
Lane 1: HeLa cell lysate,
Lane 2: HeLa treated with 500ng/mL TSA for 4 hours cell lysate,
Lane 3: NIH/3T3 cell lysate,
Lane 4: NIH/3T3 treated with 400nM TSA for 18 hours cell lysate,
Lane 5: C6 cell lysate,
Lane 6: C6 treated with 1μM TSA for 18 hours cell lysate,
Lysates/proteins at 20 µg/Lane.
Exposure time: 7 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 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 HeLa cells treated with or without 500ng/mL TSA for 4 hours with Rabbit anti-Histone H3 (acetyl K36) antibody at 1/5,000 dilution.
The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH 6.0) (high pressure) for 2 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 1/5,000 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.
ICC/IF
Immunocytochemistry analysis of HeLa cells treated with or without 500ng/mL TSA for 4 hours labeling Histone H3 (acetyl K36) with Rabbit anti-Histone H3 (acetyl K36) antibody at 1/500 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-Histone H3 (acetyl K36) antibody at 1/500 dilution in 1% BSA in PBST overnight at 4 ℃. Goat Anti-Rabbit IgG H&L (488) 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 (red) was stained at 1/100 dilution overnight at +4℃. Goat Anti-Mouse IgG H&L (594) was used as the secondary antibody at 1/1,000 dilution.
ChIP
Chromatin immunoprecipitations were performed with cross-linked chromatin from HeLa cells treated with 500ng/mL TSA for 4 hours with Histone H3 (acetyl K36) or Normal Rabbit IgG according to the ChIP protocol. The enriched DNA was quantified by real-time PCR using indicated primers. The amount of immunoprecipitated DNA in each sample is represented as signal relative to the total amount of input chromatin, which is equivalent to one.
