Western Blot of acid extracts of HeLa cells non-treated
(1) or treated with sodium butyrate (2), and recombinant
histone H3.3 (3), using RM169 at 1 ug/mL, showed a
band of histone H3 acetylated at Lysine 23 in treated HeLa.
RM169 specifically reacts to Histone H3 acetylated at Lysine 23
(K23ac). No cross reactivity with unmodified Lysine 23 (K23 ctrl),
acetylated Lysine 4 (K4ac), Lysine 9 (K9ac), Lysine 14 (K14ac),
Lysine 18 (K18ac), Lysine 27 (K27ac), Lysine 36 (K36ac), Lysine 56
(K56ac), lysine 79 (K79ac), or Lysine 122 (K122) in histone H3.

H2A.Z (Lys4) Rabbit Monoclonal Antibody (clone
RM221) (red). Actin filaments have been labeled
with fluorescein phalloidin (green).
