Description

General description

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+ MECP2 set includes a MECP2 antibody, a Normal Chicken IgY (both with bridging antibody included), and positive control primers which amplify 144 bp of a human SNRPN intron region. The MECP2 antibody and negative control IgG are supplied in a scalable "per ChIP" reaction size and can be used to functionally validate the precipitation of MECP2 associated chromatin.

MeCp2 (methyl-CpG-binding protein 2) binds methylated CpG sequences in double-stranded DNA resulting in the suppression of transcription. Although MeCp2 is not essential in stem cells, it is critical for embryonic development. This protein seems to be particularly important for mature nerve cells, where it is present in high levels. The MeCp2 protein is likely to be involved in turning off ("repressing" or "silencing") several other genes. Consistent with this role, mutations of MeCp2 are linked to Rett syndrome (RTT), a progressive neurological disorder that is one of the most common causes of mental retardation in females.

Immunogen

KLH-conjugated linear peptide corresponding to human MeCp2.

Application

Chromatin Immunoprecipitation:
Chromatin Immunoprecipitation:
Sonicated chromatin prepared from SH-SY5Ycells treated with 16 nM PMA for 72 hours (1e6 cell equivalents per IP) were subjected to chromatin immunoprecipitation using 8 µg of either Normal Chicken IgY with bridging antibody (Part No. CS207346), or 8 µg Anti-MeCP2 with bridging antibody (Part No. CS207345) and the Magna ChIP HiSens (Cat. # 17-10460). Successful immunoprecipitation of MeCP2 associated DNA fragments was verified by qPCR using ChIP Primers, human SNRPN (Part No. CS207347) as a positive locus, and GAPDH promoter primers (Part #22-004) as a negative locus. Please refer to the Magna ChIP HiSens (Cat. # 17-10460) or EZ-MagnaChIP HiSens(Cat. # 17-10461) protocol for experimental details. (Cat. # 17-10460) or EZ-MagnaChIP HiSens(Cat. # 17-10461) protocol for experimental details.


Chromatin Immunoprecipitation Analysis:
A representative lot of this antibody was used by an independent laboratory in ChIP. (Thatcher, K., et al. (2005). Hum. Mol. Genet. 14(6): 785-797.)

Western Blotting Analysis:
1 µg/mL of this antibody (prior to blending with rabbit anti-chicken bridging antibody) detected MeCp2 on 10 µg of SH-SY5Y nuclear extract.

Important Note: For western blot application of the blended antibody, use 1:680 dilution in combination with anti-rabbit HRP secondary.
