For optimal HIV recovery, PBMCs had to be freshly separated from whole blood. Short\u2010term freezing of purified PBMCs was practically advantageous and actually resulted in more rapid virus recovery. The minimal number of PBMCs necessary for virus expression was determined by dilutional cultures and varied from 10<jats:sup>2<\/jats:sup> to 10<jats:sup>6<\/jats:sup> cells. HIV expression was demonstrated initially at the cellular level by immunocytochemical detection of HIV core and envelope proteins using a mixture of monoclonal antibodies, subsequently confirmed by detection of viral antigens and reverse transcriptase (RT) in the culture supernatants. HIV recovery was not improved following induction with 5\u2010iodo\u20102\u2032\u2010deoxyuridine (IUDR) and only marginally improved following depletion of the CD8<jats:sup>+<\/jats:sup>\u2010suppressor cell population in the PBMC specimens. The overall frequency of HIV detection in cultures was 84% in healthy seropositive subjects, whereas none of the PBMCs from 72 seronegative persons yielded HIV expression.<\/jats:p>","DOI":"10.1002\/jmv.1890250102","type":"journal-article","created":{"date-parts":[[2007,3,2]],"date-time":"2007-03-02T16:13:20Z","timestamp":1172852000000},"page":"1-10","source":"Crossref","is-referenced-by-count":28,"title":["Assessment
