EEF1A1 and infection: Jurkat T-cells, separately transduced with each of the four different vectors (pN-EF1α-EGFPE/HIV-1 RRE, pN-EF1α-EGFP-2A-M10/HIV-1 RRE, pN-EF1α-EGFP/SIV RRE, pN-EF1α-EGFP-2A-M10/SIV RRE) in the previous experiment, were sorted to greater than 95% purity and challenged with HIV-1 in single-round infection assays.
