Cell purification by dual-color FACSort.
(A) Monitoring of gene expression (19.3%) 3 days after transduction of NIT. (B) CD3+ and NGFR+ T cells, termed NIT+ fraction, and (C) CD3+ and NGFR−, termed NIT− fraction, were sorted to high purity, 97.52% and 99.54%, respectively, in this example. Purity of sorted cell fractions was above 95% in all experiments. Cells of the unsorted fractions were included in the functional assays.
