(a) Eluent from the in vitro release study (days 1, 25, 46 and 94, pooled). The figure represents the mean ± SD of samples from 12 replicate MZCL IVRs with each dilution run in triplicate. (b) Vaginal fluid was collected in swabs from macaques that received MZC or MZCL IVRs (n=8) and placed in 1 mL of saline. Data is for 48h for HIV-1, 7 days for HPV and day17 HSV-2 (with exception of 1 sample which was 48h) swab sample activity. The vertical lines are the IC50 values with 95% confidence intervals. All dilutions from each vaginal swab sample were run in triplicate, and the graph shows mean ± SD.
