Applications

Our Abpromise guarantee covers the use of ab198394 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
IHC-P 1/250. Perform heat mediated antigen retrieval with Tris/EDTA buffer pH 9.0 before commencing with IHC staining protocol.
WB 1/1000. Detects a band of approximately 80 kDa (predicted molecular weight: 68 kDa).Can be blocked with Human Androgen Receptor (AR-V7 specific) peptide (ab223099).

We recommend to use 1%SDS Hot lysis prepare method.
  • Application notes
    Is unsuitable for ICC/IF.

    • Target

    • Relevance

      Belongs to the nuclear hormone receptor family. Contains nuclear receptor DNA-binding domain. Steroid hormone receptors are ligand-activated transcription factors that regulate eukaryotic gene expression and affect cellular proliferation and differentiation in target tissues. Transcription factor activity is modulated by bound coactivator and corepressor proteins. This target is a splice variant of Androgen receptor (UniProt P10275) lacking the C-terminal androgen binding site.

        Negative control: Used PBS instead of primary antibody, secondary antibody is Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/500 dilution.

        Nucleus staining on cancer cells of human prostate cancer (case#:F123132) is observed.
