Application Abreviews Notes
ICC/IF 1/200.
WB 1/1000 - 1/5000. Predicted molecular weight: 60 kDa.
IP 1/10 - 1/100.
Flow Cyt 1/10 - 1/100. ab172730-Rabbit monoclonal IgG, is suitable for use as an isotype control with this antibody.
  • Application notesIs unsuitable for ICC or IHC-P.
  • Target

    • FunctionHistone deubiquitinating component of the transcription regulatory histone acetylation (HAT) complex SAGA. Catalyzes the deubiquitination of both histones H2A and H2B, thereby acting as a coactivator. Recruited to specific gene promoters by activators such as MYC, where it is required for transcription. Required for nuclear receptor-mediated transactivation and cell cycle progression.
    • Tissue specificityModerately expressed in various tissues including heart and skeletal muscle, and weakly expressed in lung and liver.
    • Sequence similaritiesBelongs to the peptidase C19 family. UBP8 subfamily.
      Contains 1 UBP-type zinc finger.

    • Predicted band size : 60 kDa

      Lane 1: Wild-type HAP1 cell lysate (20 µg)
      Lane 2: USP22 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 - ab109435 observed at 60 kDa. Red - loading control, ab8245, observed at 37 kDa.
      ab109435 was shown to recognize USP22 when USP22 knockout samples were used, along with additional cross-reactive bands. Wild-type and USP22 knockout samples were subjected to SDS-PAGE. ab109435 and ab8245 (loading control to GAPDH) were diluted at 1/1000 and 1/10000 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 1/10000 dilution for 1 h at room temperature before imaging.
