Chromatin Immunoprecipitation: using anti-H3R2me2sK4me2 antibodies. Chromatin from one million formaldehyde cross-linked Hela cells was used with 2 μg of H3R2me2sK4me2 and 20 μl of magnetic IgG beads per immunoprecipitation. A no antibody (No Ab) control was also used. Immunoprecipitated DNA was quantified using quantitative PCR and normalized to the input chromatin.
Dot Blot: using anti-H3R2me2sK4me2 antibodies. Lane 1: R2me2. Lane 2: R2me2/K4me2. Lane 3: K4me2. Load: 0.1, 1, 0.5, 5, and 10 picomoles of peptide. Primary antibody used at a 1:1 000 dilution for 45 min at 4°C. Secondary antibody: Dylight®488 rabbit secondary antibody at 1:10 000 for 45 min at RT.
Immunofluorescence: using anti-H3R2me2sK4me2 antibodies. Tissue: HeLa cells. Fixation: 0.5% PFA. Primary antibody used at a 1:100 dilution for 1 h at RT. Secondary antibody: Dylight® 488 secondary antibody at 1:10 000 for 45 min at RT. Localization: Histone H3R2me2sK4me2 is nuclear and chromosomal. Staining: Histone H3R2me2sK4me2 is expressed in green, nuclei and alpha-tubulin are counterstained with DAPI (blue) and Dylight® 594 (red).
Western Blot: using anti-H3R2me2sK4me2 antibodies. 30 μg of C. elegans embryo cell lysate. Primary antibody used at a 1:500 dilution overnight at 4°C. Secondary antibody: IRDye800™ rabbit secondary antibody at 1:10 000 for 45 min at RT.
Western Blot: using anti-H3R2me2sK4me2 antibodies. 30 μg of NIH-3T3 histone extracts. Primary antibody used at 1:500 overnight at 4°C. Secondary antibody: IRDye800™ rabbit secondary antibody at 1:10 000 for 45 min at RT.

Background
Background
Common histone modifications include methylation of lysine and arginine, acetylation of lysine, phosphorylation of threonine and serine, and sumoylation, biotinylation, and ubiquitylation of lysine. The dimethylation of both arginine 2 (H3R2me2) and lysine 4 (H3K4me2) of H3 are both known marks to have opposing affects. R2me2 maintains transcriptional silence by silencing Set1 mediated K4 methylation, in which K4 methylation is normally associated with active chromatin. The protein arginine methyltransferase PRMT6 can methylate H3R2 in vivo, and overexpression of this enzyme downregulates Hox and Myc dependent genes, both of which are targets of H3K4 methylation.
