Biotin anti-human SSEA-4

The MC813-70 antibody reacts with a carbohydrate antigen which is named as Stage-Specific Embryonic Antigen-4 (SSEA-4). It is a terminal structure of globo-series glycolipids (NeuAcalpha2-3Galbeta1-3GalNAcbeta1-R). SSEA-4 is expressed on human teratocarcinoma cells (EC), embryonic stem cells (ESC), embryonic germ cells (EG), and preimplantation embryos, subset of mesenchymal stem cells, erythrocytes, and erythromyeloid leukemia cell line K562. The expression of SSEA-3 on human ESC is downregulated upon differentiation. SSEA-4 is also expressed by mouse on unfertilized eggs and preimplantation to early cleaved embryos.
