Abstract
Selectable Herpesvirus saimiri vectors which have a selection gene inserted into a junction region of the L- and H-DNA are described. Vectors of this type are able persistently to infect human T cells and thus are suitable for the expression of foreign genes in human T cells. An additional advantage is that no infectious virus particles are produced during this.
