Undifferentiated human Embryonal Carcinoma (EC) and Embryonic Stem (ES) cells have been shown to express very high levels of Alkaline Phosphatase isozyme that is indistinguishable from the isozyme found in liver, bone and kidney. Expression levels of AP decrease following stem cell differentiation. This clone can be used to monitor the expression of the Human Liver / Bone / Kidney isozyme of Alkaline Phosphatase (AP), and hence the differentiation status of human EC and ES cells by flow cytometry.
