Application Abreviews Notes
WB 1/1000 - 1/10000. Predicted molecular weight: 20 kDa.
IHC-P 1/50 - 1/100. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
Flow Cyt 1/100 - 1/1000.

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


IP 1/10 - 1/100.
  • Application notes
    Is unsuitable for ICC.
  • Target

    • Function
      Seems to be involved in transcriptional silencing in heterochromatin-like complexes. Recognizes and binds histone H3 tails methylated at 'Lys-9', leading to epigenetic repression. May contribute to the association of the heterochromatin with the inner nuclear membrane through its interaction with lamin B receptor (LBR). Involved in the formation of functional kinetochore through interaction with MIS12 complex proteins.
    • Sequence similarities
      Contains 2 chromo domains.
    • Post-translational
      Phosphorylated by PIM1. Phosphorylated during interphase and possibly hyper-phosphorylated during mitosis.
    • Cellular localization
      Nucleus. Associates with euchromatin and is largely excluded from constitutive heterochromatin. May be associated with microtubules and mitotic poles during mitosis.

      ab154871was shown to recognize HP1 gamma when HP1 gamma knockout samples were used, along with additional cross-reactive bands. Wild-type and HP1 gamma knockout samples were subjected to SDS-PAGE. ab154871 and ab8245 (loading control to GAPDH) were both diluted to 1/500 and 1/10,000 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.

    • Overlay histogram showing HeLa cells stained with ab154871 (red line). The cells were fixed with 4% paraformaldehyde (10 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab154871, 1/1000 dilution) for 30 min at 22°C. The secondary antibody used was Alexa Fluor® 488 goat anti-rabbit IgG (H&L) (ab150077) at 1/2000 dilution for 30 min at 22°C. Isotype control antibody (black line) was rabbit IgG (monoclonal) (0.1μg/1x106 cells) used under the same conditions. Unlabelled sample (blue line) was also used as a control. Acquisition of >5,000 events were collected using a 20mW Argon ion laser (488nm) and 525/30 bandpass filter.
