一般描述

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+ Phospho-Histone H3 (Ser28) set includes the Phospho-Histone H3 (Ser28) antibody, a Normal Rabbit IgG, and control primers which amplify a 166 bp region of the human GAPDH promoter. The Phospho-Histone H3 (Ser28) and negative controls are supplied in a scalable "per ChIP" reaction size and can be used to functionally validate the precipitation of Phospho-Histone H3 (Ser28)-associated chromatin.
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.

KLH-conjugated linear peptide corresponding to Histone H3 phosphorylated at Ser28.

应用

Chromatin Immunoprecipitation:
Representative lot data.
Sonicated chromatin prepared from untreated or colcemid-treated HeLa cells (1 X 106 cell equivalents per IP) were subjected to chromatin immunoprecipitation using either 5 ?l Normal rabbit IgG, or 5 ?l Anti-phospho-Histone H3 (Ser28) and the Magna ChIP?A Kit (Cat. # 17-610). Successful immunoprecipitation of phospho-Histone H3 (Ser28)- associated DNA fragments was verified by qPCR using ChIP Primers, human GAPDH promoter region for untreated and treated chromatin samples (Figure 2). 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.
HeLa acid extract (lane 1) and recombinant Histone H3 (lane 2) were probed with Anti-phospho-Histone H3 (Ser28) (1:2,000 dilution).
Proteins were visualized using a Donkey Anti-Rabbit IgG secondary antibody conjugated to HRP and a chemiluminescence detection system. (Figure 3)

Arrow indicates phospho-Histone H3 (Ser28) (~17 kDa).
Dot Blot Specificity Analysis:
Representative lot data.
Histone peptides with various modifications (see table) were probed with Anti-phospho-Histone H3 (Ser28). Proteins were visualized using a Donkey Anti-Rabbit IgG secondary antibody conjugated to HRP and a chemiluminescence detection system. (Figure 4)
Immunocytochemistry Analysis
Representative lot data
Confocal fluorescent analysis of HeLa cells using Anti-phospho-Histone H3 (Ser28) (Red). Actin filaments have been labeled with AlexaFluor 488 dye-Phalloidin (Green). Nucleus is stained with DAPI (Blue). This antibody positively stains the mitotic cell nucleus. (Figure 5)
Peptide Inhibition Assay: A 1:500 dilution from a representative lot was blocked by phospho-Histone H3 (Ser28) peptides, but not non-specific peptides.
