Rabbit polyclonal to EED -
Host species
Rabbit -
Specificity
ab4469 specifically recognises the four isoforms of EED following the immunoprecipitation of tagged Ezh2 from HEK293 nuclear extract. However, using HEK293 nuclear lysate ab4469 predominantly recognises non-specific bands. -

Target
-
Function
Polycomb group (PcG) protein. Component of the PRC2/EED-EZH2 complex, which methylates 'Lys-9' and 'Lys-27' of histone H3, leading to transcriptional repression of the affected target gene. 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 and CDKN2A. -
Tissue specificity
Expressed in brain, colon, heart, kidney, liver, lung, muscle, ovary, peripheral blood leukocytes, pancreas, placenta, prostate, spleen, small intestine, testis, thymus and uterus. Appears to be overexpressed in breast and colon cancer. -
Sequence similarities
Belongs to the WD repeat ESC family.
Contains 7 WD repeats. -
Developmental stage
Expression peaks at the G1/S phase boundary. -
Cellular localization
Nucleus. Chromosome. Transiently colocalizes with XIST at inactive X chromosomes. - Information by UniProt

Western blot - Anti-EED antibody (ab4469)
Lane 1: Wild-type HAP1 cell lysate (20 µg)
Lane 2: EED knockout HAP1 cell lysate (20 µg)
Lane 3: HeLa cell lysate (20 µg)
Lane 4: HepG2 cell lysate (20 µg)Lanes 1 - 4: Merged signal (red and green). Green - ab4469 observed at 55 kDa. Red - loading control, ab8245, observed at 37 kDa.
ab4469 was shown to recognize EED in wild-type HAP1 cells along with additional cross-reactive bands. No band was observed when EED knockout samples were examined. Wild-type and EED knockout samples were subjected to SDS-PAGE. ab4469 and ab8245 (loading control to GAPDH) were diluted 1/250 and 1/1000 respectively and incubated overnight at 4°C. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1/10,000 dilution for 1 hour at room temperature before imaging. -
Immunocytochemistry/ Immunofluorescence - Anti-EED antibody (ab4469)Rabbit polyclonal to EED (ab4469) on U-2 OS (Human bone osteosarcoma epithelial cell line) cells. Antibody used at 1/100.
U-2 OS cells were fixed with PFA (3.7%), permeabilised with PBS 0.1% Triton. Counterstained with Hoechst. Cells were examined with Axioplan 2 microscope (Zeiss).
Secondary antibody: donkey anti-rabbit (Cy3). -
Western blot - Anti-EED antibody (ab4469)Anti-EED antibody (ab4469) at 1/250 dilution + EED Recombinant Protein (Human) at 0.1 µg
Secondary
Goat polyclonal to Rabbit IgG - H&L - Pre-Adsorbed (HRP) at 1/3000 dilution
Performed under reducing conditions.
Predicted band size: 49 kDa
Observed band size: 80 kDa why is the actual band size different from the predicted?
ab4469 recognizes the full-length recombinant EED protein which has an expected molecular weight of 80 kDa (tagged).
