Scientific Data Images for Histone H3 [Trimethyl Lys9] Antibody (6F12-H4)

Western Blot: Histone H3 [Trimethyl Lys9] Antibody (6F12-H4) [NBP1-30141] - Whole cell protein from human HeLa, A431, mouse Neuro2A and rat PC12 cells was separated on a 4-20% gel by SDS-PAGE, transferred to 0.2 um PVDF membrane and blocked in 5% non-fat milk in TBST. The membrane was probed with 1.0 ug/ml anti-Histone h3 in block buffer and detected with an anti-mouse HRP secondary antibody using chemiluminescence. Observed molecular weight is ~15 kDa.
Immunohistochemistry-Paraffin: Histone H3 [Trimethyl Lys9] Antibody (6F12-H4) [NBP1-30141] - Histone 3 was detected in immersion fixed paraffin-embedded sections of human colon cancer using anti-human mouse monoclonal antibody (Catalog # NBP1-30141) at 1:1000 dilution overnight at 4C. Tissue was stained using the VisuCyte anti-mouse HRP polymer detection reagent (Catalog # VC001) with DAB chromogen (brown) and counterstained with hematoxylin (blue).

Immunocytochemistry/Immunofluorescence: Histone H3 [Trimethyl Lys9] Antibody (6F12-H4) [NBP1-30141] - HeLa cells were fixed for 10 minutes using 10% formalin and then permeabilized for 5 minutes using 1X PBS + 0.5% Triton X-100. The cells were incubated with anti-Histone H3 [Trymethyl Lys9] (6F12-H4) at 2 ug/ml overnight at 4C and detected with an anti-mouse DyLight 488 (green) at a 1:500 dilution. Nuclei were counterstained with DAPI (blue). Cells were imaged using a 40X objective.

Background: Histone H3

Chromatin is an arrangement of DNA and proteins which form chromosomes. Chromatin is formed from nucleosomes, which are comprised of a set of four histone proteins (H2A, H2B, H3, H4) wrapped with DNA. Chromatin is very dynamic, where post-translational modifications can regulate DNA to be copied, transcribed, or repaired.

Histones are nuclear proteins responsible for the nucleosome structure of the chromosomal fiber in eukaryotes. Changes in chromatin structure play a large role in the regulation of transcription. The chromatin fibers are compacted through the interaction of a linker histone, H1, with the DNA between the nucleosomes to form higher order chromatin structures.

Common histone modifications include methylation of lysine and arginine, acetylation of lysine, phosphorylation of threonine and serine, and sumoylation, biotinylation, and ubiquitylation of lysine. Posttranslational modifications such as acetylation of core histones regulates gene expression, thus altering protein function and regulation (1). Histone H3 is primarily acetylated at lysines 9, 14, 18, and 23 and have a theoretical molecular weight of 15 kDa. Acetylation at lysine 9 and 14 appears to control histone deposition, chromatin assembly and active transcription. Methylation of arginine residues within histone H3 has also been linked to transcription regulation. Histone H3 has been linked to various types of cancer as a biomarker through the aberrant expression of histone deacetylase (HDAC) enzymes and changes to chromatins (2-4).
