Our Abpromise guarantee covers the use of ab71982 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
ICC/IF 1/50 - 1/250.

Formaldehyde fixation is recommended. Permeabilization with Triton-X 100 is recommended for formaldehyde-fixed cells.

WB 1/2000 - 1/10000. Detects a band of approximately 38 kDa (predicted molecular weight: 31 kDa).
IP Use at 2-5 µg/mg of lysate.
IHC-P 1/100 - 1/500. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.


  • Function

    Part of the MIS12 complex, which is required for kinetochore formation and spindle checkpoint activity. Required to target ZW10 to the kinetochore at prometaphase.
  • Cellular localization

    Nucleus. Chromosome > centromere > kinetochore. Localizes to kinetochores from late prophase to anaphase.

  • Immunocytochemistry/Immunofluorescence analysis of formaldelyde-fixed HeLa cells labelling ZWINT with ab71982 at at 1/200 (1µg/ml). A FITC-conjugated goat anti-rabbit IgG (1/100) was used as the secondary antibody.
  • All lanes : Anti-ZWINT antibody (ab71982) at 0.04 µg

    Lane 1 : HeLa whole cell lysate at 50 µg
    Lane 2 : HeLa whole cell lysate at 15 µg
    Lane 3 : HeLa whole cell lysate at 5 µg
    Lane 4 : 293T whole cell lysate at 50 µg

    Developed using the ECL technique.

    Predicted band size: 31 kDa
    Observed band size: 38 kDa
    why is the actual band size different from the predicted?
    Additional bands at: 28 kDa. We are unsure as to the identity of these extra bands.

    Exposure time: 3 minutes
  • Detection of ZWINT by Western Blot of Immunprecipitate.
    ab71982 at 1µg/ml staining ZWINT in HeLa whole cell lysate immunoprecipitated using ab71982 at 3µg/mg lysate (1 mg/IP; 20% of IP loaded/lane).
    Detection: Chemiluminescence with exposure time of 30 seconds.
