title: Mammalian expression-and-transmission vector derived from Akv murine leukemia virus.
abstract: A mammalian transmission-expression vector has been constructed based on the plasmid pBR322 and using the transcriptional signals from the Akv murine leukemia virus (AkvMuLV) to control the expression of the neo gene. The transmission vector pL psi PLneo, when transfected into the psi 2 cell line, confers G-418 resistance on recipient cell clones which produce viral particles encapsidating the transcripts of the vector. Cultures of such clones produce viral particles of titers up to 10(5) cfu/ml. The pL psi PLneo vector has two unique restriction sites which can be used for the insertion of new DNA material.
