Upon completion of the primary culture, the cells are harvested, aliquoted into individual vials, and placed in liquid nitrogen storage until shipment. This product has been thoroughly tested and found to be free of the HIV Type I, Viral Hepatitis Type B and C, mycoplasma, bacteria, yeast, and fungi.
