Will a regular commercial kit (e.g., Promega, Qiagen) do the trick? If so, about how many plates of worms are sufficient per prep? Also, what's the best way to ensure that you've washed away all the bacterial worm food? We will soon need to take frequent sample aliquots from large liquid worm cultures, for counting later. Can we put these aliquots at 4 degrees for any length of time without worrying about the numbers of each stage changing? How long can the worms survive at this temperature, and will they continue to develop? (Life would be much easier if we didn't have to count the worms right at the time of sampling; the sampled worms need not remain alive, they only need to be `frozen' in time). Thanks in advance, (and belated thanks to those who have responded to my earlier posts, I'm learning a lot about everybody's favorite worm...) /sig .
