Primorigen is proud to announce the launch of a novel culture substrate* for propagation of hES and iPS cells, ensuring maintenance of pluripotency for >40 passages. It is completely human and produced under xeno-free conditions, and can be used in conjunction with serum-free stem cell media such as mTeSR™1.
