DescriptionChIPAb+™ Trimethyl-Histone H3 (Lys79) - ChIP Validated Antibody and Primer Set
OverviewAll 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+ Trimethyl-Histone H3 (Lys79) set includes the Trimethyl-Histone H3 (Lys79) antibody, a negative control normal rabbit IgG, and qPCR primers which amplify a 166 bp region of human GAPDH. The Trimethyl-Histone H3 (Lys79) and negative controls are supplied in a scalable "per ChIP" reaction size and can be used to functionally validate the precipitation of Trimethyl-Histone H3 (Lys79)-associated chromatin.

Background InformationHistones are highly conserved proteins that serve as the structural scaffold for the organization of nuclear DNA into chromatin. The four core histones, H2A, H2B, H3, and H4, assemble into an octamer (2 molecules of each). Subsequently, 146 base pairs of DNA are wrapped around the octamer, forming a nucleosome, the basic subunit of chromatin. Histone modifications regulate DNA transcription, repair, recombination, and replication. The most commonly studied modifications are acetylation, phosphorylation, methylation, and ubiquitination. Lysine methylation occurs in three distinct states, having either one (me1), two (me2) or three (me3) methyl groups attached to the amine group of the lysine side chain. Methylation of Lysine 79 in Histone 3 acts as a marker of inactive chromatin regions. Methylation by Dot1 methylase on lysine-79 (Lys79) of Histone H3 is criticial for transcriptional silencing, and it is thought that silencing proteins such as Sir3 function by blocking Dot1 methylation.

Key Applications
  • Western Blotting
  • Chromatin Immunoprecipitation (ChIP)
  • Multiplexing
Application NotesChromatin Immunoprecipitation:
Representative lot data.
Sonicated chromatin prepared from HeLa cells (1 X 10E6 cell equivalents per IP) were subjected to chromatin immunoprecipitation using either 1 µg of normal rabbit IgG, or 1 µg of Anti-trimethyl-Histone H3 (Lys79) and the Magna ChIP™ A Kit (Cat. # 17-610).
Successful immunoprecipitation of trimethyl-Histone H3 (Lys79) associated DNA fragments was verified by qPCR using Control Primers as a positive locus, and human β-globin as a negative locus (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 (Cat # 14-494) (lane2) lysates were resolved by electrophoresis, transferred to PVDF membrane and probed with Anti-trimethyl Histone H3 (Lys79) (0.1 μg/mL). Proteins were visualized using a Donkey Anti-rabbit IgG conjugated to HRP and a chemiluminescence detection system.
Arrow indicates Histone H3 (~17 kDa) (Figure 3).
Multiplex Immunoassay: Representative lot data.
Specificity of interaction of anti-trimethyl histone H3 Lys79 antibody was assayed using the Luminex® multiplex immunoassay platform. Anti-trimethyl-Histone H3 (Lys79) diluted to 0.01 µg/mL concentration was incubated with a cocktail of xMAP microspheres conjugated to the following histone H3 peptides, monomethyl Lys79, unmodified Lys79, trimethyl Lys 27, trimethyl Lys 9, trimethyl Lys79 processed and detected using standard xMAP protocols (Figure 4).

Entrez Gene Number
Entrez Gene SummaryHistones are basic nuclear proteins that are responsible for the nucleosome structure of the chromosomal fiber in eukaryotes. Nucleosomes consist of approximately 146 bp of DNA wrapped around a histone octamer composed of pairs of each of the four core histones (H2A, H2B, H3, and H4). The chromatin fiber is further compacted through the interaction of a linker histone, H1, with the DNA between the nucleosomes to form higher order chromatin structures. This gene is intronless and encodes a member of the histone H3 family. Transcripts from this gene lack polyA tails; instead, they contain a palindromic termination element. This gene is located separately from the other H3 genes that are in the histone gene cluster on chromosome 6p22-p21.3.

UniProt Number
UniProt SummaryFUNCTION: Core component of nucleosome. Nucleosomes wrap and compact DNA into chromatin, limiting DNA accessibility to the cellular machineries which require DNA as a template. Histones thereby play a central role in transcription regulation, DNA repair, DNA replication and chromosomal stability. DNA accessibility is regulated via a complex set of post-translational modifications of histones, also called histone code, and nucleosome remodeling.

SIZE: 136 amino acids; 15508 Da

SUBUNIT: The nucleosome is a histone octamer containing two molecules each of H2A, H2B, H3 and H4 assembled in one H3-H4 heterotetramer and two H2A-H2B heterodimers. The octamer wraps approximately 147 bp of DNA.

SUBCELLULAR LOCATION: Nucleus.

TISSUE SPECIFICITY: Expressed in testicular cells.

DEVELOPMENTAL STAGE: Expressed during S phase, then expression strongly decreases as cell division slows down during the process of differentiation.

PTM: Acetylation is generally linked to gene activation. Acetylation on Lys-10 impairs methylation at Arg-9. Acetylation on Lys-19 and Lys-24 favors methylation at Arg-18 (By similarity). & Citrullination at Arg-9 and/or Arg-18 by PADI4 impairs methylation and represses transcription (By similarity). & Asymmetric dimethylation at Arg-18 by CARM1 is linked to gene activation. Symmetric dimethylation at Arg-9 by PRMT5 is linked to gene repression (By similarity). & Methylation at Lys-5, Lys-37 and Lys-80 are linked to gene activation. Methylation at Lys-5 facilitates subsequent acetylation of H3 and H4. Methylation at Lys-80 is associated with DNA double-strand break (DSB) responses and is a specific target for TP53BP1. Methylation at Lys-10 and Lys-28 are linked to gene repression. Methylation at Lys-10 is a specific target for HP1 proteins (CBX1, CBX3 and CBX5) and prevents subsequent phosphorylation at Ser-11 and acetylation of H3 and H4. Methylation at Lys-5 and Lys-80 require preliminary monoubiquitination of H2B at 'Lys-120'. Methylation at Lys-10 and Lys-28 are enriched in inactive X chromosome chromatin (By similarity). & Phosphorylated at Thr-4 by GSG2/haspin during prophase and dephosphorylated during anaphase. At centromeres, specifically phosphorylated at Thr-12 from prophase to early anaphase. Phosphorylated at Ser-11 during the whole mitosis. Phosphorylation at Ser-11, which is linked to gene activation, prevents methylation at Lys-10 but facilitates acetylation of H3 and H4. Phosphorylated at Ser-29 by MLTK isoform 1, RPS6KA5 or AURKB during mitosis or upon ultraviolet B irradiation (By similarity). & Phosphorylation at 'Ser-11' is crucial for chromosome condensation and cell-cycle progression during mitosis and meiosis. In addition phosphorylation at 'Ser-11' is important during interphase because it enables the transcription of genes following external stimulation, like stress or growth factors. Phosphorylation at 'Ser-11' is also an essential regulatory mechanism for neoplastic cell transformation. Phosphorylation at 'Ser-11' by AURKB/Aurora-B mediates the dissociation of HP1 proteins (CBX1, CBX3 and CBX5) from heterochromatin. & Ubiquitinated (By similarity).

SIMILARITY: Belongs to the histone H3 family.
