Opis

Opis ogólny

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+ EZH2, clone AC22 antibody/primer set includes the EZH2, clone AC22 antibody, a negative control antibody (purified mouse IgG), and qPCR primers which amplify a 135 bp region within the promoter of the human MYT-1 gene. The EZH2, clone AC22 antibody and negative control antibodies are supplied in a scalable "per ChIP" reaction size and can be used to functionally validate the precipitation of EZH2-associated chromatin.

EZH2 is a polycomb group (PcG) protein that is a catalytic subunit of the PRC2/EED-EZH2 complex, which methylates ′Lys-9′ (H3K9me) and ′Lys-27′ (H3K27me) of histone H3, leading to transcriptional repression of the affected target gene. Able to mono-, di- and trimethylate ′Lys-27′ of histone H3 to form H3K27me1, H3K27me2 and H3K27me3, respectively. Compared to EZH2-containing complexes, it is more abundant in embryonic stem cells and plays a major role in forming H3K27me3, which is required for embryonic stem cell identity and proper differentiation. The PRC2/EED-EZH2 complex may also serve as a recruiting platform for DNA methyltransferases, thereby linking two epigenetic repression systems. Genes repressed by the PRC2/EED-EZH2 complex include HOXC8, HOXA9, MYT1, CDKN2A and retinoic acid target genes. EZH2 can also methylate non-histone proteins such as the transcription factor GATA4 and the nuclear receptor RORA. Regulates the circadian clock via histone methylation at the promoter of the circadian genes. Essential for the CRY1/2-mediated repression of the transcriptional activation of PER1/2 by the CLOCK-ARNTL/BMAL1 heterodimer; involved in the di and trimethylation of ′Lys-27′ of histone H3 on PER1/2 promoters which is necessary for the CRY1/2 proteins to inhibit transcription.

Specyficzność

Not tested in other species. The immunogen sequence is identical in a wide range of animal and plant species, so broad cross-reactivity is expected.

Recognizes EZH2, MW: ~85-100 kDa.

Immunogen

EZH2, clone AC22 purified antibody is made against a GST fusion protein corresponding to amino acids 353-451 of human EZH2.

Epitope: a.a. 353-451

Zastosowanie

Chromatin Immunoprecipitation:
Representative lot data.
Sonicated chromatin prepared from HeLa S3 cells (4 X 10⁶ cell equivalents per IP) was subjected to chromatin immunoprecipitation using 1 µg of either a normal mouse IgG or Anti-EZH2, clone AC22 antibody and the Magna ChIP G Kit (Cat. # 17-611).
Successful immunoprecipitation of EZH2-associated DNA fragments was verified by qPCR using GAPDH promoter (negative) and MYT-1 promoter (positive) primers (Please see figures). 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 G ChIP (Cat. # 17-409) or EZ-ChIP (Cat. # 17-371) protocol for experimental details.

Immunoprecipitation Analysis:
Representative lot data.
HeLa nuclear cell extract was Immunoprecipitated with either anti-EZH2, clone AC22 or mouse IgG and then resolved by electrophoresis, transferred to PVDF and probed with Cat. # 05-1319 anti-EZH2, clone BD43 (1:1000 dilution).
Proteins were visualized using a goat anti-mouse secondary antibody conjugated to HRP (Cat. # AP124P) and a chemiluminescence detection system.
