Specificity / Sensitivity

Phospho-Histone H3 (Ser10) (D7N8E) XP® Rabbit mAb recognizes endogenous levels of histone H3 protein only when phosphorylated at Ser10. This antibody detects phosphorylation at Ser10 in the presence of acetylated or methylated Lys9, but not in the presence of phosphorylated Thr11. This antibody does not cross-react with histone H3 phosphorylated at Ser28.

Species Reactivity:

Human, Mouse, Rat, Monkey

Species predicted to react based on 100% sequence homology

Hamster, Xenopus, S. cerevisiae

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding phosphorylated Ser10 of human histone H3 protein.

Background

Modulation of chromatin structure plays an important role in the regulation of transcription in eukaryotes. The nucleosome, made up of DNA wound around eight core histone proteins (two each of H2A, H2B, H3, and H4), is the primary building block of chromatin (1). The amino-terminal tails of core histones undergo various posttranslational modifications, including acetylation, phosphorylation, methylation, and ubiquitination (2-5). These modifications occur in response to various stimuli and have a direct effect on the accessibility of chromatin to transcription factors and, therefore, gene expression (6). In most species, histone H2B is primarily acetylated at Lys5, 12, 15, and 20 (4,7). Histone H3 is primarily acetylated at Lys9, 14, 18, 23, 27, and 56. Acetylation of H3 at Lys9 appears to have a dominant role in histone deposition and chromatin assembly in some organisms (2,3). Phosphorylation at Ser10, Ser28, and Thr11 of histone H3 is tightly correlated with chromosome condensation during both mitosis and meiosis (8-10). Phosphorylation at Thr3 of histone H3 is highly conserved among many species and is catalyzed by the kinase haspin. Immunostaining with phospho-specific antibodies in mammalian cells reveals mitotic phosphorylation at Thr3 of H3 in prophase and its dephosphorylation during anaphase (11).

Chromatin Immunoprecipitation Image 1: Phospho-Histone H3 (Ser10) (D7N8E) XP® Rabbit mAb Expand Image
HeLa cells were cultured and either left untreated (left panel) or treated with Nocodazole #2190 (100 ng/ml, 16 hr; right panel). Chromatin immunoprecipitations were performed with cross-linked chromatin and Phospho-Histone H3 (Ser10) (D7N8E) XP® Rabbit mAb or Normal Rabbit IgG #2729 using SimpleChIP® Enzymatic Chromatin IP Kit (Magnetic Beads) #9003. The enriched DNA was quantified by real-time PCR using SimpleChIP® Human GAPDH Promoter Primers #4471 and SimpleChIP® Human γ-Actin Promoter Primers #5037. The amount of immunoprecipitated DNA in each sample is represented as signal relative to the total amount of input chromatin, which is equivalent to one.
