| Function | In eukaryotes, DNA is wrapped around histone octamers to form the basic unit of chromatin structure. The octamer is composed of histones H2A, H2B, H3 and H4, and it associates with approximately 200 base pairs of DNA to form the nucleosome. The association of DNA with histones results in dense packing of chromatin, which restricts proteins involved in gene transcription from binding to DNA. p300 preferentially acetylates Histone H3 at lysines 14 and 18 and Histone H4 at lysines 5 and 8. PCAF in its native form, primarily acetylates Histone H3 at lysine 14 to a monoacetylated form, and less efficiently acetylates Histone H4 at lysine 8. Histone H4 may also be acetylated at lysines 12 and 16, and the involvement of acetylated H4 with Histones H2A, H2B and H3 suggests that acetylated histones may be involved in dynamic chromatin remodeling. |

WB
Western blot analysis of Histone H3 (tri methyl K27) on different lysates with Rabbit anti-Histone H3 (tri methyl K27) antibody at 1/1,000 dilution. Lane 1: HeLa cell lysate, Lane 2: SH-SY5Y cell lysate, Lane 3: HCT 116 cell lysate, Lane 4: NIH/3T3 cell lysate, Lane 5: C6 cell lysate, Lane 6: MCF7 cell lysate, Lane 7: MCF7 treated with 10μM EED226 for 72 hours cell lysate, Lysates/proteins at 20 µg/Lane. Exposure time: 25 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 human colon tissue with Rabbit anti-Histone H3 (tri methyl K27) antibody at 1/1,000 dilution. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH 6.0) 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 1/1,000 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.
ICC/IF
Immunocytochemistry analysis of HeLa cells labeling Histone H3 (tri methyl K27) with Rabbit anti-Histone H3 (tri methyl K27) antibody 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-Histone H3 (tri methyl K27) antibody at 1/100 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 with Histone H3 (tri methyl K27) 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.| Application Notes | WB:1:1000 IHC:1:1000 ICC/IF:1:100 ChIP:Use 0.5~2 μg for 25 μg of chromatin. |
