  • 功能
    Component of the NuA4 histone acetyltransferase complex which is involved in transcriptional activation of select genes principally by acetylation of nucleosomal histones H4 and H2A. This modification may both alter nucleosome - DNA interactions and promote interaction of the modified histones with other proteins which positively regulate transcription. May be required for transcriptional activation of E2F1 and MYC target genes during cellular proliferation. The NuA4 complex ATPase and helicase activities seem to be, at least in part, contributed by the association of RUVBL1 and RUVBL2 with EP400. May regulate ZNF42 transcription activity.
  • 组织特异性

  • Detection of Human p400 by Western Blot of Immunprecipitate. Lane 1: Irrelevant antibody used for precipitation. Lane 2: ab70301 at 0.04µg/ml staining p400 in HeLa whole cell lysates immunoprecipitated using ab70301 at 3µg/mg lysate (1 mg/IP; 1/4 of IP loaded/lane). Lane 3: Control IgG used for precipitation.

  • ab70301 (1/200) staining p400 in asynchronous HeLa cells (green). Cells were fixed in paraformaldehyde, permeabilized using 0.5% Triton X-100/PBS and counterstained with DAPI in order to highlight the nucleus (red). For further experimental details please refer to Abreview.

  • ICC/IF image of ab70301 stained HepG2 cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab70301, 1µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

Thank you for contacting us. As discussed on phone we unfortunately do not sell small sizes of our products. The reason is that; we have over 70,000 products in our catalogue and having the small sized sample of each would be difficult to keep. How...
