Zusammenfassung: | Caenorhabditis elegans is a model system widely used in fundamental research. Even though, nematodes are easy to maintain in the laboratory, obtaining large populations of worms require a lot of work and is time consuming. Furthermore, because C. elegans are mainly hermaphrodite it is even more complicated to obtain large amounts of males which make high-throughput experiments using C. elegans males very challenging.
In order to overcome these limitations, we developed affordable and rapid methods to:
1) grow large synchronous worm populations
2) easily obtain large amounts of males
We developed a culture method on plates to grow big synchronized worm populations with the standard incubators used on all worm labs. We also established an easy filtration method allowing to obtain large male populations in an hour. After filtering, the worm population contains more than 90% of adult males and no adult hermaphrodites since all the contaminants are larva and embryos.
The culture and the filtering methods we developed are easy to implement and require a very limited investment in equipment and consumables beside the standard one present in worm labs. In addition, this filtering method could be applied to nematode's species similar in size to C. elegans.
