Jump-or-Die System

This system also uses Bak as apoptosis inducing selection marker together with the tet-on promoter, which is to be stably integrated in the cell-line genome. However, this construct also includes an upstream bacterial attachment site (attB) and a downstream SV40 polyadenylation site (SV40PA). The target gene eGFP is combined with phage attachment site (attP) and another SV40PA but without promoter. The target plasmid is co-transfected with integrase PhiC31o into the cell line. Therefore the target gene can only be expressed if integrated into the cells’ genome, and the stop-codon and SV40PA following the target gene stop the expression of bak, ensuring the survival of the cell while other cells not expressing the target gene undergo induced apoptosis.
