Applications Key: W=Western Blotting, IF-IC=Immunofluorescence (Immunocytochemistry), F=Flow Cytometry
Specificity / Sensitivity
Phospho-Histone H3 (Ser10) (D2C8) XP® Rabbit mAb detects endogenous levels of histone H3 only when phosphorylated at Ser10; however, this antibody does not detect phosphorylated Ser10 when Lys9 is acetylated or methylated. This antibody does not cross-react with histone H3 phosphorylated at Ser28.
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Ser10 of human histone H3.
Peptide dot blot analysis demonstrating Phospho-Histone H3 (Ser10) (D2C8) XP® Rabbit mAb antibody specificity. Antibody binding to pre-coated histone H3 peptides is shown using Phospho-Histone H3 (Ser10) (D7N8E) XP® Rabbit mAb #53348,
Phospho-Histone H3 (Ser10) (D2C8) XP® Rabbit mAb #3377, and Phospho-Histone H3 (Ser10) Antibody #9701. As shown, Phospho-Histone H3 (Ser10) (D2C8) XP® Rabbit mAb detects histone H3 phosphorylated on Ser10; however, this antibody does not detect histone H3 phosphorylated on Ser10 when Lys9 is acetylated or methylated. In addition, this antibody does not cross-react with histone H3 phosphorylated on Ser28.
Western blot analysis of extracts from HeLa cells, either untreated or treated with nocodazole (100 ng/ml for 18 hours), using Phospho-Histone H3 (Ser10) (D2C8) XP® Rabbit mAb #3377 (upper) or Histone H3 Antibody #9715 (lower). Phospho-specificity of the antibody is shown by further treatment of the lysate with λ phosphatase.
Confocal immunofluorescent analysis of HeLa cells using Phospho-Histone H3 (Ser10) (D2C8) XP® Rabbit mAb (green). Actin filaments have been labeled with DY-554 phalloidin (red). Blue pseudocolor = DRAQ5® #4084 (fluorescent DNA dye).
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 post-translational 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).
