This line produces a vector that can infect mouse cells. Psi2 DAP cells produce a vector that encodes the human placental alkaline phosphatase gene and the neomycin resistance gene. The line was derived from Psi2 cells by insertion of a recombinant retrovirus genome (DAP). Cells infected with the vector produced by Psi2 DAP cells express histochemically detectable alkaline phosphatase which can be used as a marker to follow their fate in vivo. The cells may produce helper virus. To assay for helper virus, and for other retrovirus techniques, see Cepko, C.L.
