1. Viability and viable cell recovery of cryopreserved PBMC after variable periods of storage in liquid nitrogen.
Viability and viable cell recovery of cryopreserved PBMC after variable periods of storage in liquid nitrogen. The graphs show the data from the laboratory with typical performance among the six participating laboratories. Data were generated using multiple aliquots of cryopreserved PBMC from a single donor tested after 1 to 15 months of storage in liquid nitrogen. The lines depict the regression of the outcome measure as a function of time.
