Fig. 3. Marker expression in menstrual blood and vaginal secretion stains. Graphs depict the expression level of the seven markers at three time points during the menstrual
cycle: menstrual blood stains (A) and vaginal secretion stains taken 3 (B) and 7 days (C) post-menstruation. The average marker expression level (RFUs) for each donor is
shown. Values on the y-axis represent RFUs, and donors are located on the x-axis.
