一般說明
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+ Dimethyl-Histone H4 (Arg3) Symmetric set includes the Dimethyl-Histone H4 (Arg3) Symmetric antibody, a Normal Rabbit IgG, and control primers which amplify a 110 bp region of ChIP Primers, human β-globin. The Dimethyl-Histone H4 (Arg3) Symmetric and negative controls are supplied in a scalable "per ChIP" reaction size and can be used to functionally validate the precipitation of Dimethyl-Histone H4 (Arg3) Symmetric-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). Histones are modified post-translationally by the actions of enzymes in both the nucleus and cytoplasm. These modifications, which include acetylation, phosphorylation, methylation, and ubiquitin-ation, occur predominantly on the N-terminal and C-terminal tails that extend beyond the nucleosome core particle. Arginine modifications of histones proteins are mediated by two classes of protein arginine methyltransferases (PRMTs), class I and II. Class I PRMTs place two methyl groups on the one nitrogen atom of the arginine guanidino group, resulting in an asymmetric modification. In contrast class II PRMTs place two methyl groups on two nitrogen atoms of the guanidino group producing a symmetric dimethylation. Although there are exceptions, asymmetric modifications are typically associated with transcription activation while symmetric modifications are most commonly associated with transcriptional repression.

應用
Chromatin Immunoprecipitation:
Representative lot data.
Sonicated chromatin prepared from HeLa cells (1 X 10E6 cell equivalents per IP) were subjected to chromatin immunoprecipitation using 1 µg of either Normal rabbit IgG or 0.7 µg of Anti-Dimethyl-Histone H4 (Arg3) Symmetric and the Magna ChIP A Kit (Cat. # 17-610). Successful immunoprecipitation of Dimethyl-Histone H4 (Arg3) Symmetric associated DNA fragments was verified by qPCR using ChIP Primers, human β-globin as a positive locus, and GAPDH promoter primers (22-004) 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 H4 (Lane 2) were probed with Anti-Dimethyl-Histone H4 (Arg3) Symmetrical (0.1μg/mL). Proteins were visualized using a Donkey Anti-Rabbit IgG secondary antibody conjugated to HRP and a chemiluminescence detection system.
Arrow indicates Histone H4 (~13 kDa). (Figure 3).
Note: An uncharacterized band at ~58 kDa has been observed in some lysates.
Dot Blot Analysis:
Representative lot data.
Histone peptides with various modifications (see table below) were probed with Anti-Dimethyl-Histone H4 (Arg3) Symmetrical (1:2,000 dilution). Proteins were visualized using a Donkey Anti-Rabbit IgG secondary antibody conjugated to HRP and a chemiluminescence detection system. (Figure 4). See table below.
Immunocytochemistry Analysis:
Representative lot data.
Confocal fluorescent analysis of A431 and HeLa cells using Anti-Dimethyl-Histone H4 (Arg3) Symmetrical (Red). Actin filaments have been labeled with Alexa Fluor 488 dye Phalloidin (Green). Nucleus is stained with DAPI (Blue). This antibody positively stains the nucleus. (Figure 5).
