I would like to know if somebody has ever tried to use C.briggsae cDNA as probe to clone a C.elegans homologue. I've tried to hybridized a southern blot of C.elegans DNA with such a cDNA probe and the best I can get is a wide smear (wh ereas with a C.elegans gene probe, I get a very specific signal). The conditio ns I used for hybridisation were 5% SDS/0.5MNaPO4 pH 7,2/0.5mM EDTA at 43C. If one of you have obtained good result with that approach, could you please send me your conditions? Is there some special thing that I should know about C.briggsae (codon usage? repetitive sequences? etc?) Thanks in advance for any help you can provide S.Tremblay Laval University Quebec Ca 3000jger@vm1.ulaval.ca .
