目标/特异性 | Tri-Methyl-Histone H3 (Lys9) (D4W1U) Rabbit mAb detects endogenous levels of histone H3 when tri-methylated on Lys9. This antibody shows some cross-reactivity with histone H3 that is di-methylated on Lys9, but does not cross-react with non-methylated or mono-methylated histone H3 Lys9. This antibody does not detect tri-methyl histone H3 Lys9 when the adjacent Ser10 residue is phosphorylated during mitosis. In addition, this antibody does not cross-react with methylated histone H3 Lys4, Lys27, Lys36, or Lys79. |

Chromatin immunoprecipitations were performed with cross-linked chromatin from 4 x 106 HeLa cells and either 10 μl of Tri-Methyl-Histone H3 (Lys9) (D4W1U) Rabbit mAb or 2 μl of Normal Rabbit IgG #2729 using SimpleChIP® Enzymatic Chromatin IP Kit (Magnetic Beads) #9003. The enriched DNA was quantified by real-time PCR using SimpleChIP® Human GAPDH Exon 1 Primers #5516, SimpleChIP® Human AFM Intron 1 Primers #5098, SimpleChIP® Human MYT-1 Exon 1 Primers #4493, and SimpleChIP® Human α Satellite Repeat Primers #4486. 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. | |
Confocal immunofluorescent analysis of interphase (left) or mitotic (right) HeLa cells, untreated (upper) or λ phosphatase-treated (lower), using Tri-Methyl-Histone H3 (Lys9) (D4W1U) Rabbit mAb (green) and β-Actin (8H10D10) Mouse mAb #3700 (red). Blue pseudocolor = DRAQ5® #4084 (fluorescent DNA dye). As shown, this antibody does not detect tri-methyl histone H3 Lys9 in mitotic cells when the adjacent Ser10 residue is phosphorylated. | |
Western blot analysis of extracts from various cell lines using Tri-Methyl-Histone H3 (Lys9) (D4W1U) Rabbit mAb. | |
Antibody specificity was determined by western blotting. HeLa and NIH/3T3 cell lysates were probed with Tri-Methyl-Histone H3 (Lys9) (D4W1U) Rabbit mAb (Panel A) or Tri-Methyl-Histone H3 (Lys9) (D4W1U) Rabbit mAb pre-adsorbed with 1.5 μM of various competitor peptides (panels B-M). As shown, only the tri-methyl histone H3 (Lys9) peptide (panel E) competed away binding of the antibody. |
