PowerStem ESPro1 is an easy to use serum-free medium for cultivation of embryonic stem cells of mice (mES cells). These pluripotent cells are derived from blastocysts and they can be established to a permanent cell culture. After injection into blastocysts in chimeras, they can form all tissues, including germ cells. The mES cells largely maintain their undifferentiated state and can be integrated into the germ line.

• Store at –20 °C

It contains purified proteins, lipids, salts, amino acids, trace elements, attachment factors, hormones and growth factors in an optimised formulation. It is fully chemically defined and contains no peptones or hydrolysates.

Suitable for serum-free cultivation of embryonic stem cells of mice (mES cells), while maintaining the undifferentiated state. It is especially designed for the serum-free generation of knockout-mice from genetically modified mES cells. It has also been proven to support the serum-free cultivation and expansion of tumour progenitor cells.
