ChIPAb+ Acetyl Histone H3 (Lys23)-ChIP Validated Antibody and Primer Set

产品说明

一般描述

Histone H3 is one of the five main histone proteins involved in the structure of chromatin in eukaryotic cells. Featuring a main globular domain and a long N-terminal tail, H3 is involved with the structure of the nucleosomes of the ′beads on a string′ structure.

The N-terminal tail of histone H3 protrudes from the globular nucleosome core and can undergo several different types of epigenetic modifications that influence cellular processes. These modifications include the covalent attachment of methyl or acetyl groups to lysine and arginine amino acids and the phosphorylation of serine or threonine.
All ChIPAb+ antibodies are individually validated for chromatin precipitation, every lot, every time. Each ChIPAb+ antibody set includes control primers (tested every lot by qPCR) to biologically validate your IP results in a locus-specific context. The qPCR protocol and primer sequences are provided, allowing researchers to validate ChIP protocols when using our antibody in their chromatin context. Each set also includes a negative control antibody to ensure specificity of the ChIP reaction.
The ChIPAb+ Acetyl Histone H3 (Lys23) set includes the Acetyl Histone H3 (Lys23) antibody, a normal rabbit serum, and control primers which amplify a 166 bp region of human GAPDH promoter. The Acetyl Histone H3 (Lys23) and negative controls are supplied in a scalable "per ChIP" reaction size and can be used to functionally validate the precipitation of Acetyl Histone H3 (Lys23)-associated chromatin.

特异性

Histone H3 acetylated on lysine 23. Does not recognize unacetylated recombinant histone H3

免疫原

Ovalbumin-conjugated, synthetic peptide (KQLAS_AcKAARK-C) corresponding to amino acids 18-27 of yeast histone H3 acetylated on lysine 23 with a C-terminal cysteine added for conjugation purposes

应用

Chromatin Immunoprecipitation:
Representative lot data.
Sonicated chromatin prepared from HeLa cells (1 X 10E6 cell equivalents per IP) were subjected to chromatin immunoprecipitation using 2 µL of either normal rabbit serum or 2 µL Anti-acetyl-Histone H3 (Lys23)and the Magna ChIP^® A Kit (Cat. # 17-610). Successful immunoprecipitation of acetyl-Histone H3 (Lys23) associated DNA fragments were verified by qPCR using Control Primers specific for the human GAPDH promoter region as a positive locus, and MyoD primers as a negative locus. 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.
Acid extracts from sodium butyrate treated HeLa cells (Lane 1, Catalog # 17-305) and recombinant Histone H3 (Lane 2, Catalog # 14-494) were probed with Anti-acetyl-Histone H3 (Lys23) (1:100,000 dilution).
Arrow indicates acetyl histone H3 (~17 kDa)
Dot Blot:
Representative lot data.
40 ng and 4ng amounts of histone peptides with various modifications (see table 1) were transferred to PVDF membrane and probed with Anti-Acetyl-Histone H3 (Lys23) antibody (1:2000 dilution). Proteins were visualized using a goat anti-rabbit IgG conjugated to HRP and a chemiluminescence detection system. Image from a 60 second exposure is shown.
