Application Abreviews Notes
IP Use at an assay dependent concentration.
WB Use at an assay dependent concentration. Detects a band of approximately 72-80 kDa (predicted molecular weight: 46 kDa).
  • Application notes
    Is unsuitable for Flow Cyt,ICC/IF or IHC-P.
  • Target

    • Tissue specificity

      Expressed by all types of trophoblasts as early as 9 weeks of development. Specific for trophoblastic cells except for amniotic epithelium. In adult tissues, the expression is limited to a few epithelial cell types but is found on a variety of carcinoma.
    • Sequence similarities

      Contains 6 LRR (leucine-rich) repeats.
      Contains 1 LRRCT domain.
      Contains 1 LRRNT domain.

    • Form

      5T4 is a 72 kDa transmembrane glycoprotein that exhibits restricted expression in human and mouse adult tissues, is upregulated on many carcinomas and tumour expression correlates with poorer clinical outcome in ovarian, gastric and colorectal cancers. mES cells lack cell surface expression of the 5T4 antigen, and both protein and mRNA are rapidly upregulated following induction of differentiation. This proteins expression correlates with downregulation of OCT-4 and Tra-1–60 (Ward et al., 2006).
