Each unit (vital = proliferating flask, or cryo = cryopreserved) contains more than 500,000 cells. Each cell strain is performance tested by extensive growth assays and inspection of cell morphology. Provitro guarantees a minimum of 10 population doublings from most normal human cell culture.
Cells test negative for HIV-1 DNA, hepatitis B DNA, hepatitis C DNA, mycoplasma, bacteria, yeast and fungi. Provitro guarantees the homogeneity of each cell type according to celltype-specific test markers. Each unit comes with a certificate specifying the results of quality control for this cell culture.
