We have developed a vector that allows high and transactivable express
ion of inserted genes. The vector contains a transcription unit in whi
ch the LTR from HN flanks a multicloning site. The plasmid is based on
the EBV p205 plasmid, which allows stable replication in human cells.
The ability of the vector to express an exogenous DNA in human cells
has been tested using the firefly luciferase gene. (C) 1994 Academic P
