Effect of Lemon Juice, Lime Juice, Vinegar, Nonoxynol-9 (N-9), and Triton X-100 on Viability of Cervical Explant Tissues. Effects of lemon juice, lime juice, vinegar, Triton X-100, nonoxynol-9 (N-9), and UC781 on viability of cervical explant tissues. Presented are the percent viability for tissues treated with lemon juice (1-20%), lime juice (0.32-20%), vinegar (6%), Triton X-100 (0.00005-5%), nonoxynol-9 (N-9; 100 μg/mL), and UC781 (100 μM), compared to donor-matched, untreated controls (defined as 100%). Tissues were exposed from 2 hours to overnight. Each bar represents data from 1 to 6 donors. Bars indicate mean ± SD for each product/concentration. The concentration of juice or vinegar is expressed as percent (%) solution (v/v).
