From: Impact of cryopreservation on tetramer, cytokine flow cytometry, and ELISPOT
Results of the three assays on CMV seronegative versus seropositive donors. (A and B) Tetramer results on fresh-shipped and cryopreserved PBMC samples, respectively. (C and D) CFC results on fresh-shipped and cryopreserved PBMC samples, respectively. (E and F) ELISPOT results on fresh-shipped and cryopreserved PBMC samples, respectively. The dotted line represents the suggested cutoff based upon maximum specificity for sensitivity ≥90%, or that which obtains maximum sensitivity if maximum sensitivity <90%.
