This product has not been tested with paraffin sections.


  • FunctionTranscriptional repressor of genes that require a bHLH protein for their transcription.
  • Tissue specificityExpressed in fetal heart and brain tumors.
  • Sequence similaritiesContains 1 basic helix-loop-helix (bHLH) domain.
    Contains 1 Orange domain.
  • DomainHas a particular type of basic domain (presence of a helix-interrupting proline) that binds to the N-box (CACNAG), rather than the canonical E-box (CANNTG).
    The C-terminal WRPW motif is a transcriptional repression domain necessary for the interaction with Groucho/TLE family members, transcriptional corepressors recruited to specific target DNA by Hairy-related proteins.

Anti-HES5 antibody images

  • ab25374 staining the cortex of e14.5 mouse embryo by IHC-Fr.  The tissue was frozen and cut into 10 µm slices on a cyrostat then fixed and blocked prior to incubating with the primary antibody (diluted 1/100) for 90 minutes.  A fluorescent conjugated secondary antibody was incubated with the sample for 30 minutes.  HES-5 is shown in red in the nuclear regions; the blue staining is Hoechst nuclear counter stain.
