Our Abpromise guarantee covers the use of ab89222 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
ELISA Use at an assay dependent concentration.
WB Use a concentration of 1 - 5 µg/ml. Predicted molecular weight: 70 kDa.
IHC-P Use a concentration of 3 µg/ml. Antigen retrieval is not essential but may optimise staining.


  • FunctionEnhances the androgen receptor transcriptional activity in prostate cancer cells. Ligand-independent coactivator of the peroxisome proliferator-activated receptor (PPAR) gamma.
  • Tissue specificityWidely expressed. Also detected in adipose tissues and in different cell lines. Isoform Beta is only expressed in testis.
  • Involvement in diseaseDefects in NCOA4 are a cause of thyroid papillary carcinoma (TPC) [MIM:188550]. TPC is a common tumor of the thyroid that typically arises as an irregular, solid or cystic mass from otherwise normal thyroid tissue. Papillary carcinomas are malignant neoplasm characterized by the formation of numerous, irregular, finger-like projections of fibrous stroma that is covered with a surface layer of neoplastic epithelial cells. Note=A chromosomal aberration involving NCOA4 is found in thyroid papillary carcinomas. Inversion inv(10)(q11.2;q11.2) generates the RET/NCOA4 (PTC3) oncogene that has been found in sporadic and radiation-associated post-Chernobyl thyroid papillary carcinomas.

  • Anti-NCOA4 antibody (ab89222) at 5 µg/ml + immunogen at 0.2 µg
    developed using the ECL technique

    Predicted band size : 70 kDa
    Observed band size : 38 kDa (why is the actual band size different from the predicted?)
  • Anti-NCOA4 antibody (ab89222) at 5 µg/ml + HeLa nuclear extract at 50 µg
    developed using the ECL technique

    Predicted band size : 70 kDa
    Observed band size : ~60 kDa (why is the actual band size different from the predicted?)
    Additional bands at : ~13 kDa. We are unsure as to the identity of these extra bands.
