^aSupernatants of each infection experiments were tested for the presence of p24gag in duplicates at several time post infection (day 1 to 24) and the peak concentration is presented. Results represent means ± SD of at lease two experiments.

^bCotton rat cell clones expressing human CD4 with CXCR4 (CCRT K4), or with CCR5 (CCRT C6 and VCRT C17).

^cHIV-1 viral isolates X4-tropic (MN) and R5-tropic (BAL and US1).

^dnot determined.
