Specificity / Sensitivity

Histone H3 (1B1B2) Mouse mAb recognizes endogenous levels of total histone H3 protein.

Source / Purification

Monoclonal antibody is produced by immunizing animals with a peptide specific to the carboxy terminus of human histone H3 protein.

IHC-P (paraffin)

IHC-P (paraffin)

Immunohistochemical analysis of paraffin-embedded human lung carcinoma using Histone H3 (1B1B2) Mouse mAb.

IF-IC

IF-IC

Confocal immunofluorescent analysis of HeLa cells using H3 (1B1B2) Mouse mAb (green) and β-Actin (13E5) Rabbit mAb #4970 (red). Blue pseudocolor = DRAQ5® #4084 (fluorescent DNA dye).

Flow Cytometry

Flow Cytometry

Flow cytometric analysis of HeLa cells using Histone H3 (1B1B2) Mouse mAb (blue) compared to the concentration-matched Mouse (G3A1) mAb IgG1 Isotype Control #5415 (red). Anti-mouse IgG (H+L), F(ab')2 Fragment (Alexa Fluor® 488 Conjugate) #4408 was used as a secondary antibody.

Western Blotting

Western Blotting

Western blot analysis of extracts from various cell lines using Histone H3 (1B1B2) Mouse mAb.

Chromatin IP

Chromatin IP

Chromatin immunoprecipitations were performed with cross-linked chromatin from 4 x 106 HeLa cells and either 10 μl of Histone H3 (1B1B2) Mouse mAb or 2 μl of 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 Exon 1 Primers #5516, SimpleChIP® Human RPL30 Exon 3 Primers #7014, SimpleChIP® Human MYT-1 Exon 1 Primers #4493, and SimpleChIP® Human α Satellite Repeat Primers #4486. 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.

IHC-P (paraffin)

IHC-P (paraffin)

Immunohistochemical analysis of paraffin-embedded human breast carcinoma using Histone H3 (1B1B2) Mouse mAb.

IHC-P (paraffin)

IHC-P (paraffin)

Immunohistochemical analysis of paraffin-embedded human colon carcinoma using Histone H3 (1B1B2) Mouse mAb.

IHC-P (paraffin)

IHC-P (paraffin)

Immunohistochemical analysis of paraffin-embedded human ovarian carcinoma using Histone H3 (1B1B2) Mouse mAb.

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 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).
