Descripción

Descripción general

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.

Aplicación

Dot Blot Specificity Analysis:
AbSurance Histone H3 Antibody Specificity Arrays (Cat. #: 16-667 and 16-665) containing peptides to all key histone modification sites, were probed with Anti-trimethyl Histone H3 (Lys79) Antibody Antibody ; dilution 1:5000. Proteins were visualized using a goat anti-mouse IgG (H+L) conjugated to HRP and a chemiluminescence detection system.


Multiplex Immunoassay
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 mg/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.

Anti-trimethyl Histone H3 (Lys79) Antibody is a rabbit polyclonal antibody for detection of trimethyl Histone H3 (Lys79). It has been tested for use in Western blotting, Dot blots, and Multiplex assays.
