Structure and expression of transduced genes. (A) Primary structure of EGFP-MP1 is shown. The position of the A2-restricted antigenic peptide, MP1^58-66, is shown in the black box. (B) Expression of transduced EGFP-MP1 (open curve) was analyzed by flow cytometric analysis using the FL1 channel. Untransduced aAPCs were used as a control (filled curve).
