Fig. 3. Dynamic expression of Prd in adult accessory glands. Expression patterns of Prd protein in accessory glands from a 1-day- (A,B), 5-day- (C,D), or 10-day-old (E,F) virgin male, or from a 5-day old-virgin male mated with females for the next 5 days (G,H) are shown at low (A,C,E,G) and high (B,D,F,H) magnification. Accessory glands were stained with rabbit anti-Prd antiserum. mc, main cells; sc, secondary cells.
