Virus DNA - Where can i find purified virus DNA (Jun/07/2002 )

I know that a lot of people work with cell lines that contain viruses. Because we only need a small amount for positive control, i would like to know which company keep this typeof DNA. I already know that ABI sells it, but it costs too much, since it comes from England. Any suggestion ? (I'm looking for herpes simplex virus type 1, epstein-barr virus type 1 and cytomegalovirus)

I get viral DNA standard from either ABI (Columbia MD), which I guess you've tried, as well as BBI Diagnostics (Boston Biomedica) - http://www.bbii.com/research_services.htm#virology
