Application Abreviews Notes
IHC-P 1/50 - 1/100. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
WB 1/500 - 1/1000. Detects a band of approximately 35 kDa (predicted molecular weight: 34 kDa).
IP 1/10.
  • Application notes
    Is unsuitable for Flow Cyt or ICC/IF.
  • Target

    • Function

      Transcription factor that forms a trimeric complex with OCT4 on DNA and controls the expression of a number of genes involved in embryonic development such as YES1, FGF4, UTF1 and ZFP206 (By similarity). Critical for early embryogenesis and for embryonic stem cell pluripotency.
    • Involvement in disease

      Defects in SOX2 are the cause of microphthalmia syndromic type 3 (MCOPS3) [MIM:206900]. Microphthalmia is a clinically heterogeneous disorder of eye formation, ranging from small size of a single eye to complete bilateral absence of ocular tissues (anophthalmia). In many cases, microphthalmia/anophthalmia occurs in association with syndromes that include non-ocular abnormalities. MCOPS3 is characterized by the rare association of malformations including uni- or bilateral anophthalmia or microphthalmia, and esophageal atresia with trachoesophageal fistula.
    • Sequence similarities

      Contains 1 HMG box DNA-binding domain.
    • Post-translational

      Sumoylation inhibits binding on DNA and negatively regulates the FGF4 transactivation.
    • Cellular localization
