Background Information

ATOH1, also named as Protein atonal homolog 1 or BHLHA14, is a 364 amino acid protein, which contains 1 bHLH (basic helix-loop-helix) domain. ATOH1,as a transcriptional regulator in the nucleus activates E box-dependent transcription in collaboration with TCF3/E47, but the activity is completely antagonized by the negative regulator of neurogenesis HES1. ATOH1 plays a role in the differentiation of subsets of neural cells by activating E box-dependent transcription.

ATOH1 antibody was tested on embryonic chicken tissue. Staining showed nuclear localisation in inner ear vestibular crista in sox2 positive prosensory region of 6 day old embryo

  • Applications: Immunofluorescence
  • Primary Antibody Dilution: 1:300
  • Cell Tissue Type: Embryonic chicken inner ear tissue

Roland (Verified Customer) (09-17-2020)

We tested several ATOH1 antibodies and this is the only one which turned out to be specific as confirmed bei knockdown experiments.

  • Applications: Western Blot
  • Cell Tissue Type: human cancer cells

Biren (Verified Customer) (08-31-2020)

I used human GBM stem cells as a negative control to validate the specificity of this antibody. The cells used were confirmed by RNAseq to not express ATOH1, yet all cells were positively stained at the previously used concentration of 1/500, indicating that this antibody is not specific.

  • Applications: Immunofluorescence
  • Primary Antibody Dilution: 1/500
  • Cell Tissue Type: human glioblastoma stem cells

Erithelgi (Verified Customer) (09-25-2019)

The antibody detects a band of the expected size, in cells that induce GFP-ATOH1 under a DOX promoter. No bands detected in non-induced cells.

  • Applications: Western Blot,
  • Primary Antibody Dilution: 1:1000
  • Cell Tissue Type: medulloblastoma
