Ivanovski Institute of Virology, Moscow, Russia. SO Virus Genes. 1995;10(1):45-51. Unique Identifier : AIDSLINE GENBANK/M15390 AB For monitoring retroviral infection on the gene level, we propose the use of quantitative PCR with two internal standards: one for a fragment of the viral genome and the other for the host cell marker gene. The standards (one for HIV and the other for a human DNA marker gene HLA-DQ alpha) were constructed by PCR-mediated joining of DNA fragments and were found to be effective in quantitative PCR despite rather different structures of amplified fragments in target and standard DNAs. The number of HIV DNA copies was found to be 2-500 per 1000 lymphocytes in blood from HIV-infected patients and up to 5000+ per 1000 cells in chronically infected cell lines. The degree of infection thus measured was found to change over the course of treatment.
