SDS-PAGE (upper panels) and Western blot analysis (lower panels) of crude extracts from reproductive organs.

<p>Reproductive organs include male accessory glands and testes, and female accessory glands and ovaries, dissected from virgin individuals of different ages. Numbers indicate days after emergence. Only male extracts of both species present an intense cross-reacting band at the expected molecular weight of OBP10. Molecular weight markers (<b>M</b>) are as in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0030040#pone-0030040-g002" target="_blank">Figure 2</a>.
