RESUMO

Recombinant retroviruses are frequently used in the transfer and analysis of genes. This report describes new retrovirus vectors that incorporate a cDNA copy of a cell surface antigen to function as a selectable marker. By using techniques based on quantitative cell surface immunofluorescence, these vectors allow the rapid detection and isolation of infected cells. These vectors also allow the rapid detection of packaging cell lines producing large amounts of recombinant retroviruses. Potential applications of these vectors are demonstrated.
