Description

General description

Polycomb group proteins are important for maintaining transcriptional silencing. One conserved PcG complex, PRC2, is composed of several proteins including the histone methyltransferase EZH2, the WD-repeat protein EED (Embryonic ectoderm development), and the Zn-finger protein Suz12. Transcriptional repression mediated by EED involves histone deacetylation, while the EZH2 methylates histone H3 on lysine 27. EED protein is present in four isoforms. These EED isoforms selectively associate with distinct EZH2-containing complexes, resulting in differential targeting of their associated methyltransferase activity. These complexes play a role in Hox gene silencing, X-inactivation, germline development, stem cell pluripotency and cancer metastasis.

RIPAb+ antibodies are evaluated using the RNA Binding Protein Immunoprecipitation (RIP) assay. Each RIPAb+ antibody set includes a negative control antibody to ensure specificity of the RIP reaction and is verified for the co-immunoprecipitation of RNA associated specifically with the immunoprecipitated RNA binding protein of interest. Where appropriate, the RIPAb+ set also includes quantitative RT-PCR control primers (RIP Primers) to biologically validate your IP results by successfully co-precipitating the specific RNA targets, such as messenger RNAs. The qPCR protocol and primer sequences are provided, allowing researchers to validate RIP protocols when using the antibody in their experimental context. If a target specific assay is not provided, the RIPAb+ kit is validated using an automated microfluidics-based assay by enrichment of detectable RNA over control immunoprecipitation.

Specificity

Not tested in other species.

This antibody recognizes mouse EED, (~30-65 kDa).

Immunogen

Recombinant fusion protein of full length murine EED tagged with MBP.

Application

Immunoprecipitation from RIP lysate:
Representative lot data.
RIP lysate from HeLa cells (~2 X 10E7 cell equivalents per IP) was subjected to immunoprecipitation using 5 µg of either a normal mouse IgG, (Cat. #CS200621), or 5 µg of Anti-EED antibody (Cat. # CS204372). Ten percent of the precipitated proteins (lane 1: mouse IgG, lane 3: EED) and HeLa whole cell lysate (lane 2) were resolved by electrophoresis, transferred to nitrocellulose and probed with Anti-EED antibody (Cat. # CS204372, 1:5000). Proteins were visualized using One-Step IP-Western kit (GenScript Cat. # L00232).
Arrow indicates EED.
Western Blot Analysis:
Representative lot data.
A431 cell lysate was resolved by electrophoresis, transferred to nitrocellulose and probed with Anti-EED (1:5,000 dilution). Proteins were visualized using a goat anti-mouse IgG conjugated to HRP and a chemiluminescence detection system.
Arrow indicates EED (~50 kDa).

Quality

RNA Binding Protein Immunoprecipitation: Representative lot data.
RIP Lysate prepared from HeLa cells (2 X 10E7 cell equivalents per IP) were subjected to immunoprecipitation using 5 µg of either a normal mouse IgG or 5 µg of Anti-EED antibody and the Magna RIP® RNA-Binding Protein Immunoprecipitation Kit (Cat. # 17-700).
Successful immunoprecipitation of EED-associated RNA was verified by qPCR using RIP Primers lincSFPQ.
Please refer to the Magna RIP (Cat. # 17-700) or EZ-Magna RIP (Cat. # 17-701) protocol for experimental details.

Storage and Stability

Stable for 1 year at -20°C from date of receipt.
Handling Recommendations: Upon receipt, and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance. Note: Variabillity in freezer temperatures below -20°C may cause glycerol containing solutions to become frozen during storage.

Analysis Note

Control
Includes negative control normal mouse IgG antibody and control primers specific for the cDNA of human lincRNA SFPQ.

Other Notes

Concentration: Please refer to the Certificate of Analysis for the lot-specific concentration.
