Description
Details
BioLite™ surface markers allow for direct immunofluorescent staining of live, unfixed pluripotent stem cell populations. The antibodies undergo meticulous application testing and validation to ensure they are sterile, non-toxic, contain no sodium azide, and are free of culture pathogens. Colonies stained with BioLite antibodies are able to continue in culture with no adverse effect on proliferation and differentiation potential when compared to untreated cells.
Background Stage-specific embryonic antigen-1 (SSEA-1) is a carbohydrate epitope expressed upon the surface of early mouse embryos, murine embryonal carcinoma (EC), murine embryonic stem (ES), and murine and human germ (EG) cells. No immunoreactivity is evident with undifferentiated human EC and ES cells. Differentiation of human EC results in an increase in SSEA-1 expression, while in the mouse expression is diminished. SSEA-1 is associated with cell adhesion, migration and differentiation.
