Description générale
All 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.

Histones 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.
Spécificité

Application
Chromatin 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).
