FIG 1.
(A) Typical electropherogram depicting the test principle. Four types of mass peaks are resolved: 80-bp molecular weight marker (MWM); single-stranded V3 probe (ss-probe); hybrid of patient-derived V3 sequence and probe (duplex). Residual double-stranded probe material serves as the ds-control. PM, perfect match; 1 and 2 indicate relative peak distances for tropism calculation. (B) Representative section of the list of V3 loop nucleotide sequences after grouping according to their relatedness to the probe candidate in the top line: HIV-1JR-CSF.
