FIG. 6.
Intra-assay variability across experimental conditions. Intra-assay variability was measured using the %CV for replicate p24 measurements. Data shown represent the median %CV and interquartile range for p24 release determined at the assay SOFT for seven laboratories using their preferred explant method under each experimental condition (), alongside the total %CV for the study (
). (a) Source of virus/medium; (b) effect of microbicide PRO 2000; (c) growth of different HIV-1 isolates; (d) tissue type. Significant differences were determined using the Mann-Whitney test.
