RM151 specifically reacts to Histone H3 dimethylatedat Lysine 9 (K9me2). No cross reactivity with non-modified Lysine 9 (H3 1-19), monomethylated Lysine 9 (K9me1), trimethylated Lysine 9 (K9me3), or other methylations in Histone H3.
Western Blot of recombinant histone H3.3 (1) and acid extracts of HeLa cells (2), using RM151 at 0.5 ug/mL, showed a band of histone H3 dimethylated at Lysine 9 (K9me2) in HeLa cells.
ChIP performed on HeLa cells using H3K9me2 antibody (RM151, 5ug). Real-time PCR was performed using primers specific to the gene indicated.
Immunocytochemistry of HeLa cells treated withsodium butyrate, using Dimethyl-Histone H3(Lys9) Rabbit mAb RM151 (red). Actin filaments havebeen labeled with fluorescein phalloidin (green).
