Some people in our department have started using YoYo to discriminate between
ss and ds DNA. Apparently it works extremely well, but I don't know if it is
useable/has been used with agarose gels. And of course no recipe, sorry. I
think there was a JBC article by Benbow within the last year or so about it .
