Stem and iPS cell selection: quantitation of surface marker (SSEA1) and intracellular GFP

Abstract

Consistent and reliable propagation of undifferentiated stem cells is of particular interest in cell line development and drug screening. The Genetix ClonePix FL technology, already established for the rapid one-step identification and isolation of hybridomas and cell lines for biopharmaceutical production, can be used to isolate and collect stem cells expressing specific cell surface and intracellular proteins.
