Improved Helper Virus-Free Packaging System for HSV Amplicon Vectors Using an ICP27-Deleted, Oversized HSV-1 DNA in a Bacterial Artificial Chromosome
1 Apr 2001
Abstract excerpt
Herpes simplex virus type 1 (HSV-1) amplicons are prokaryotic plasmids containing one or more transcriptional units and two cis-acting HSV-1 sequences: a viral origin of DNA replication and a viral DNA cleavage/packaging signal. In the presence of HSV-1 "helper" functions, amplicons are replicated and packaged into HSV-1 virions. Despite recent improvements in packaging methods, stocks of amplicon vectors are...
