FIG. 4.
As a consequence of uniformly high cell viability in the seventh QAP PBMC specimens, there was no association between viability or yield and immune function (determined by the IFN-γ response to the CEF peptide pool, as measured by ELISPOT assay). Linear regression and 95% confidence interval curves are shown (for data taken from the single-donor PBMC only). SFC, spot-forming cells.
