Description

General description

Monoclonal Anti-diMethyl-Histone H3 (diMe-Lys9) (H3K9me2) (mouse IgG1 isotype) is derived from the hybridoma 5E5-G5 produced by the fusion of mouse myeloma cells and splenocytes from BALB/c mice immunized with a dimethylated (diMe-Lys9) peptide corresponding to the N-terminus of human histone H3, conjugated to KLH. Histones H3 and H4 are the core histones forming nucleosome, which is the fundamental unit of chromatin. H3 and H4 remodified by methylation and are highly methylated in mammalian cells.

Immunogen

dimethylated (diMe-Lys⁹) peptide corresponding to the N-terminus of human histone H3, conjugated to KLH. The isotype is determined by ELISA using Mouse Monoclonal Antibody Isotyping Reagents (Sigma ISO-2).

Application

Monoclonal Anti-diMethyl-Histone H3 (diMe-Lys9) (H3K9me2) antibody produced in mouse may be used in several immunochemical techniques including immunoblotting (~17 kDa) and immunofluorescence.

Biochem/physiol Actions

Histones are subjected to extensive covalent modifications, including phosphorylation, methylation, acetylation and ubiquitination thought to play an important role in development and in cancer. Histone methylation, is a complex, dynamic process involving various biological processes including transcriptional regulation, chromatin condensation, mitosis and heterochromatin assembly. Moreover, lysine residues can be mono-, di-, and tri-methylated, adding further complexity to the regulation of chromatin structure. Conserved lysine residues in the N-terminal tail domains of histone H3, Lys⁴, Lys⁹ and Lys²⁷ are the preferred sites of methylation. Methylation of H3 at Lys⁹ is a modification intrinsically linked to epigenetic silencing and heterochromatin assembly.

Physical form
