Strain Genotype Description
AC552 aph-2(tm6471)/hT2 [bli-4(e937) let-?(q782) qIs48] (I;III). Heterozygous. Homozygous lethal deletion chromosome balanced by bli-4- and GFP-marked translocation. Heterozygotes are WT with pharyngeal GFP signal, and segregate WT GFP, arrested hT2 aneuploids, and non-GFP tm4743 homozygotes (Egl, Mel, but do not display adult-onset sterility). Homozygous hT2[bli-4 let-? qIs48] inviable. Pick WT GFP and check for correct segregation of progeny to maintain. Only heterozygous animals should propagate. aph-2(tm6471) deletion allele was generated by the National BioResource Project of Japan, part of the International C. elegans Gene Knockout Consortium.
