RM140 specifically reacts to Histone H3 monomethylated at Lysine 4 (K4me1). No cross reactivity with dimethylated Lysine 4 (K4me2), trimethylated Lysine 4 (K4me3), or other methylations in histone H3.
Western Blot of recombinant histone H3.3 (1) and acid extracts of HeLa cells (2), using RM140 at 0.5 ug/mL, showed a band of histone H3 monomethylated at Lysine4 (K4me1) in HeLa cells.
ChIP performed on HeLa cells using H3K4me1 antibody (RM140, 5ug). Real-time PCR was performed using primers specific to the gene indicated.
Immunocytochemistry of HeLa cells treated withsodium butyrate, using Monomethyl-Histone H3(Lys4) Rabbit mAb RM140 (red). Actin filaments have been labeled with fluorescein phalloidin (green).
