ab172730 - Rabbit monoclonal IgG, is suitable for use as an isotype control with this antibody.


WB 1/10000 - 1/50000. Detects a band of approximately 36 kDa (predicted molecular weight: 36 kDa).
  • Application notes
    Is unsuitable for IHC-P.
  • Target

    • Function
      PP2A can modulate the activity of phosphorylase B kinase casein kinase 2, mitogen-stimulated S6 kinase, and MAP-2 kinase.
    • Sequence similarities
      Belongs to the PPP phosphatase family. PP-1 subfamily.
    • Post-translational
      Reversibly methyl esterified on Leu-309. Carboxyl methylation may play a role in holoenzyme assembly. It varies during the cell cycle. Demethylated by PME1 (in vitro).
      Phosphorylation of either threonine (by autophosphorylation-activated protein kinase) or tyrosine results in inactivation of the phosphatase. Auto-dephosphorylation has been suggested as a mechanism for reactivation.
    • Cellular localization
      Cytoplasm. Nucleus. Chromosome > centromere. Cytoplasm > cytoskeleton > spindle pole. In prometaphase cells, but not in anaphase cells, localizes at centromeres. During mitosis, also found at spindle poles.

      ab168371 was shown to specifically react with PPP2CB in wild-type HAP1 cells. No band was observed when PPP2CB knockout samples were examined. Wild-type and PPP2CB knockout samples were subjected to SDS-PAGE. Ab168371 and ab18058 (Mouse anti-Vinculin loading control) were incubated overnight at 4°C at 1/10,000 dilution and 1/10,000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed ab216776 secondary antibodies at 1/10,000 dilution for 1 hour at room temperature before imaging.

    • Detection of PPP2CB by Western Blot of Immunprecipitate.
      293T cell lysate immunoprecipitated using ab168371 at 1/10 dilution.
      For WB detection ab168371 at 1/10000 dilution was used.
