Western blot analysis of Histone H3 (mono methyl K27) on different lysates with Rabbit anti-Histone H3 (mono methyl K27) antibody at 1/1,000 dilution.
Lane 1: MCF7 cell lysate,
Lane 2: SH-SY5Y cell lysate,
Lane 3: HeLa cell lysate,
Lane 4: A549 cell lysate,
Lane 5: NIH/3T3 cell lysate,
Lane 6: PC-12 cell lysate,
Lysates/proteins at 20 µg/Lane.
Exposure time: 1 minute 50 seconds;
4-20% SDS-PAGE gel.
Proteins were transferred to a PVDF membrane and blocked with 2% BSA/TBST for 1 hour at room temperature. The primary antibody at 1/1,000 dilution was used in TBST at 4℃ overnight. Goat Anti-Rabbit IgG - HRP Secondary Antibody at 1/50,000 dilution was used for 1 hour at room temperature.
ICC/IF
Immunocytochemistry analysis of NIH/3T3 cells labeling Histone H3 (mono methyl K27) with Rabbit anti-Histone H3 (mono methyl K27) 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 (mono methyl K27) 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.
ICC/IF
Immunocytochemistry analysis of C6 cells labeling Histone H3 (mono methyl K27) with Rabbit anti-Histone H3 (mono methyl K27) antibody at 1/250 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 (mono methyl K27) antibody at 1/250 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.
FC
Flow cytometric analysis of MCF7 cells labeling Histone H3 (mono methyl K27).
Cells were fixed and permeabilized. Then stained with the primary antibody (1/500) (red) compared with Rabbit IgG Isotype Control (green). After incubation of the primary antibody at +4℃ for an hour, the cells were stained with a 488 conjugate-Goat anti-Rabbit IgG Secondary antibody at 1/1,000 dilution for 30 minutes at +4℃. Unlabelled sample was used as a control (cells without incubation with primary antibody; black).
ChIP
Chromatin immunoprecipitations were performed with cross-linked chromatin from MCF7 cells with Histone H3 (mono methyl K27) / Competitor C / 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.
