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.

The TRA-1-81 antibody reacts with a pluripotent-stem-cell-specific antigen expressed on the surface of human embryonal carcinoma (EC), embryonic germ (EG), embryonic stem (ES), and induced pluripotent stem (iPS) cells. The expression of TRA-1-81 antigen is stage-specific; as human EC and ES cells undergo differentiation, expression of TRA-1-81 antigen is lost, making it a widely used marker to characterize human ES cells and to monitor their differentiation.
