Application Abreviews Notes
WB 1/1000 - 1/10000. Predicted molecular weight: 66 kDa.
  • Application notes
    Is unsuitable for Flow Cyt,ICC/IF,IHC-P or IP.
  • Target

    • Function

      The PR65 subunit of protein phosphatase 2A serves as a scaffolding molecule to coordinate the assembly of the catalytic subunit and a variable regulatory B subunit.
    • Sequence similarities

      Belongs to the phosphatase 2A regulatory subunit A family.
      Contains 15 HEAT repeats.
    • Domain

      Each HEAT repeat appears to consist of two alpha helices joined by a hydrophilic region, the intrarepeat loop. The repeat units may be arranged laterally to form a rod-like structure.

      ab154833 was shown to recognize PPP2R1B when PPP2R1B knockout samples were used, along with additional cross-reactive bands. Wild-type and ProteinX knockout samples were subjected to SDS-PAGE. ab154833 and ab8245 (loading control to GAPDH) were diluted 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 ab216776secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.

    Customer reviews and Q&As


    We have not tested 7288-1 or 7301-1 for cross reactivity with PP2AA alpha, however, we have only observed one band in our in-house testing with 7288-1 and we have detected only 2 isoforms of PP2AA beta with 7301-1. It is possible they could react, based on the fact that the immunogen sequences for 7288-1 and 7301-1 have 78% and 75% homology with PP2AA alpha (respectively), but typically homology needs to be at about 85% for there to be good cross-reactivity.
