SV1930 C. elegans swsn-8(he273 he287 [LoxN exon 3 + LoxN last intron]) I; heSi208 V; heSi141 X. Show Description
heSi208 [eft- 3p::LoxP::NLS(egl-13)::tagBFP2::tbb-2 UTR::LoxP::NLS(egl-13)::mCherry::tbb-2 3'UTR] V. heSi141 [hlh-8p::CRE] X. he273 he287 homozygotes are Egl since they cannot form a functioning vulva due to swsn-8 inactivated in the mesoderm lineage by hlh-8p::CRE expression. LoxN sites in the endogenous swsn-8 locus facilitate inducible knockout of swsn-8. Reference: van der Vaart A, et al. Sci Adv 2020 May 20;6(21):eaay3823. PMID: 32494730

ccIs4251 [(pSAK2) myo-3p::GFP::LacZ::NLS + (pSAK4) myo-3p::mitochondrial GFP + dpy-20(+)] I.

Avoid picking viable aneuploids that often appear larger and longer than wild-type.
