Our Abpromise guarantee covers the use of ab94977 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 Use a concentration of 1 µg/ml. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
WB Use a concentration of 1 µg/ml. Detects a band of approximately 47 kDa (predicted molecular weight: 47 kDa).
ICC/IF Use at an assay dependent concentration.


  • FunctionTranscription factor that binds preferentially to the recognition sequence which consists of two distinct half-sites, ('GCAT') and ('TAAT'), separated by a nonconserved spacer region of 0, 2, or 3 nucleotides. Positively regulates the genes under the control of corticotropin-releasing hormone (CRH) and CRH II promoters.
  • Tissue specificityExpressed specifically in the neuroectodermal cell lineage.
  • Sequence similaritiesBelongs to the POU transcription factor family. Class-3 subfamily.
    Contains 1 homeobox DNA-binding domain.
    Contains 1 POU-specific domain.

Figure B: Non-transfected control under the same staining conditions by ICC/IF (Immunocytochemistry/immunofluorescence). Cells were fixed with Paraformaldehyde, permeabilized with Triton X-100 0.3% in PBS for 10 mins at 21°C and blocked with 5% normal Goat serum for 1 hour at 25°C. Samples were incubated with primary antibody (1/1000 in 5% Goat serum) for 22 hour at 4°C. An Alexa Fluor®488-conjugated Goat anti-Rabbit IgG polyclonal (1/500) was used as the secondary antibody for 2 hours at 25°C.
