Application
Research Sub CategoryHistones
Research CategoryEpigenetics & Nuclear Function
This ChIPAb+ Acetyl-Histone H4 (Lys5) -ChIP Validated Antibody & Primer Set conveniently includes the antibody & the specific control PCR primers.
Chromatin Immunoprecipitation:
Sonicated chromatin prepared from untreated HeLa cells (1 X 106 cell equivalents per IP) were subjected to chromatin immunoprecipitation using 2 µL of either a negative control supernatant , or 2 µL of Anti-Acetyl-Histone H4 (Lys5) and the Magna ChIP® A Kit (Cat. # 17-610).
Successful immunoprecipitation of acetyl-Histone H4 (Lys5) associated DNA fragments was verified by qPCR using control Primers flanking the human GAPDH promoter, or primers amplifying the promoter of human β-globin, which is transcriptionally inactive in HeLa cells (Please see figures).
Data is presented as percent input of each IP sample relative to input chromatin for each amplicon and ChIP sample as indicated.
Please refer to the EZ-Magna ChIP™ A (Cat. # 17-408) or EZ-ChIP™ (Cat. # 17-371) protocol for experimental details.
Western Blot Analysis:
Representative lot data.
Lysates from HeLa cells untreated or sodium butyrate treated (Lanes 1 and 2 respectively) were probed with anti-acetyl-Histone H4 (Lys5) (1:1,000 dilution).
Proteins were visualized using goat anti-rabbit. (Please see figures).
Western Blot Analysis/Peptide Inhibition: Representative lot data.
Sodium butyrate treated HeLa acid extract was resolved by electrophoresis, transferred to PVDF membrane and probed with Anti-Acetyl-Histone H4 (Lys5) (1:1000 dilution).
To demonstrate specificity, serum was preincubated with modified Histone H4 peptides:
Lane 1: No peptide
Lane 2: Acetyl-Histone H4 (K5) (Cat. # 12-343)
Lane 3: Acetyl-Histone H4 (K8) (Cat. # 12-344)
Lane 4: Acetyl-Histone H4 (K12) (Cat. # 12-345)
Lane 5: Acetyl-Histone H4 (K16) (Cat. # 12-346)
Lane 6: Acetyl-Histone H4 (K5, 8, 12, 16) (Cat. # 12-353)
Lane 7: Histone H4 (Cat. # 12-347)
Proteins were visualized using a donkey anti-rabbit IgG conjugated to HRP and visualized using a chemiluminescence detection system. (Please see figures).

General description
Histone H4 is one of the 5 main histone proteins involved in the structure of chromatin in eukaryotic cells. Featuring a main globular domain and a long N terminal tail H4 is involved with the structure of the nucleosomes of the ′beads on a string′ structure. Acetylation of histone H4 occurs at several different lysine positions in the histone tail and is performed by a family of enzymes known as Histone Acetyl Transferases (HATs).
