We describe the use of the monoclonal antibodies TG30 (CD9) and GCTM-2 for the combined detection of cell surface antigens via fluorescence activated cell sorting (FACS) for the identification and enrichment of live human embryonic stem cells (hESC) using positive selection and also the use of negative selection to purge hESCs from a mixed cell population.
