Western blot analysis of whole cell lysates from HeLa, NIH/3T3, H-4-II-E and COS cells, using Di-Methyl-Histone H3 (Lys9) Antibody.
Chromatin immunoprecipitations were performed with cross-linked chromatin from 4 x 10 6 HeLa cells and either 20 μl of Di-Methyl-Histone H3 (Lys9) Antibody or 2 μl 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 AFM Intron 1 Primers #5098, SimpleChIP ® Human α Satellite Repeat Primers #4486, SimpleChIP ® Human RPL30 Exon 3 Primers #7014, and SimpleChIP ® Human GAPDH Exon 1 Primers #5516. 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.
