Abstract
Epstein–Barr virus (EBV)-based vectors are extrachromosomal vectors carrying a replicational origin, oriP (about 2200 bp) and a replication initiation factor (EBNA-1) which are sufficient for autonomous replication. Because one disadvantage of these vectors is their large sizes, we examined the effect of partial deletion of oriP on the effectiveness of the EBV-based vectors, using an enhanced green fluorescent protein (EGFP) as a reporter to monitor gene expression. Results indicated that 954 bp-deleted mini-oriP is useful in primate cells since the vector showed high efficiency of stable transfection, a high ratio of EGFP-positive cells, and high recovery of intact plasmid DNA from transfected cells.
