Figure 6. Duration of topically applied antibodies in the vagina.

Figure 6

A fifty percent reduction in the concentration of topically applied rabbit antibodies was detected in vaginal washes collected 1 hr post-inoculation compared to a 2 min time point. Antibody levels decreased further over time. The limit of detection was 7.8 ng/ml. (A) Concentration of rabbit IgG (µg/ml) in mouse vaginal washes was determined in duplicate by capture ELISA. (B) The percent of antibody remaining relative to the average 2 minute value is shown for each time point. Results are combined from two experiments and each animal was used for a single time point (n = 2–3 mice per time point).
