Strain Genotype Species Description
CGC140 goa-1(n499)/tmC20 [unc-14(tmIs1219) dpy-5(tm9715)] I. C. elegans Homozygous lethal mutation balanced by Dpy- and myo-2p::Venus-marked inversion. Heterozygotes are paralyzed Unc and Egl with relatively dim pharyngeal GFP (Venus) expression. Heterozygotes segregate heterozygous non-Dpy GFP+ paralyzed Unc and Egl, non-GFP embryonic lethal (homozygous n499), and Dpy with brighter GFP+ (tmC20 homozygous). This strain is difficult and time consuming to maintain. Gives relatively few heterozygotes. Remove Dpy from plate to prevent them from taking over. Heterozygotes tend to stack up in parallel clumps. Populations can be enriched by transferring these clumps to new plates and allowing Dpy (tmC20 homozygotes) to crawl out into bacterial lawn, and then picking away Dpy or transferring the clump of Hets to another plate. Derived by balancing n499 from parental strain MT1102 over tmC20 from FX30179.
XA780 gna-2(qa705)/goa-1(n499) I. C. elegans Heterozygotes are Egl and Paralyzed. Segregate embryonic lethals (n499) homozygotes. Segregates WT animals that lay only non-refractile eggs that fail to hatch. Pick paralyzed Egl worms to maintain (eggs on the plate should all be pale brown and non-refractile; presence of refractile eggs indicates a recombination has occurred). XA780 recombines at a frequency of about 1%.
