Maintain at 20C or cooler. qIs26 [lag-2::GFP + rol-6(su1006)]. set-2 mutation balanced by glp-1- and dpy-19-marked recombination suppressor. qIs26 was integrated into qC1 and in the process made qC1 homozygous lethal. Heterozygotes are Rollers and GFP+ in the distal tip cell, and segregate WT Rol, lethal qC1 homozygotes, and set-2(syb2085) homozygotes (Mrt phenotype at 25C -- viable but homozygotes will become sterile in successive generations). Pick WT GFP+ Rol and check for correct segregation of progeny to maintain. set-2(syb2085) mutant animals that express a catalytically inactive form of SET-2, the C. elegans SET1 homolog. set-2(syb2085) homozygotes are not long-lived on OP50.
