Strain Genotype Species Description
MD4195 unc-119(ed3) III; bcSi69 IV. C. elegans bcSi69 [hsp-16.41p::dCas9::SV40-NLS::HA::GS-linker::SV40-NLS::GFP::GFP::SV40-NLS::mai-2 3’UTR + Cbr-unc-119(+)] IV. [NOTE: MD4195 can be maintained at 20C instead of 15C because it does not carry an array with guide RNAs targeting essential genes.] Generated in parental strain EG8081. Reference: Memar N, et al. In vivo labeling of endogenous genomic loci in C. elegans using CRISPR/dCas9. MicroPubl Biol. 2022 Dec 13;2022:10.17912/micropub.biology.000701. doi: 10.17912/micropub.biology.000701. PMID: 36606081; PMCID: PMC9807462.
MD4571 unc-119(ed3) III; bcSi69 IV; bcEx1367. C. elegans bcSi69 [hsp-16.41p::dCas9::SV40-NLS::HA::GS-linker::SV40-NLS::GFP::GFP::SV40-NLS::mai-2 3’UTR + Cbr-unc-119(+)] IV. bcEx1367 [U6p::rrn-4(sgRNAs1-4 targeting the rrn-4 locus) + rol-6(su1006)]. Maintain at 15C. Pick Rollers to maintain. After heat shock, distinct spots of GFP fluorescence are visible in the nucleus. bcEx1367 array contains a PCR product of 4 different guide RNAs targeting rrn-4 (around 100 repeats of rrn-4 on LG V).

C. elegans bcSi69 [hsp-16.41p::dCas9::SV40-NLS::HA::GS-linker::SV40-NLS::GFP::GFP::SV40-NLS::mai-2 3’UTR + Cbr-unc-119(+)] IV. bcEx1368 [U6p::rrn-1(sgRNAs1-4 targeting the rrn-1 locus) + rol-6(su1006)]. Maintain at 15C. Pick Rollers to maintain. After heat shock, distinct spots of GFP fluorescence are visible in the nucleus. bcEx1368 array contains a PCR product of 4 different guide RNAs targeting rrn-1 (around 100 repeats of rrn-1 on LG I).

C. elegans bcSi69 [hsp-16.41p::dCas9::SV40-NLS::HA::GS-linker::SV40-NLS::GFP::GFP::SV40-NLS::mai-2 3’UTR + Cbr-unc-119(+)] IV. bcEx1370 [U6p::rrn-4(sgRNAs1-4 targeting the rrn-1 locus) + U6p::rrn-4(sgRNAs1-4 targeting the rrn-4 locus) + rol-6(su1006)]. Maintain at 15C. Pick Rollers to maintain. After heat shock, distinct spots of GFP fluorescence are visible in the nucleus. bcEx1370 array contains a PCR product of 4 different guide RNAs targeting rrn-1 (around 100 repeats of rrn-1 on LG I) and a PCR product of 4 different guide RNAs targeting rrn-4 (around 100 repeats of rrn-4 on LG V).

MD5004 drp-1(dx230[drp-1::mNeonGreen]) IV. C. elegans mNeonGreen tag inserted into the variable region of endogenous drp-1 locus (internal tag). N- and C-terminal fusions of DRP-1 cause a block in mitochondrial fission (acting as dominant-negatives), whereas internally-tagged DRP-1 protein has close to wild-type activity. Generated in N2 background. Reference: Lambie EJ & Conradt B. MicroPubl Biol. 2025 May 8;2025:10.17912/micropub.biology.001588. PMID: 40415901.
MD5016 egl-1(dx243[mSG::egl-1]) V. C. elegans Coding sequence for monomeric StayGold (mSG) inserted at the beginning of the 2nd exon of the endogenous egl-1 locus. mSG::EGL-1 retains close to wild-type activity (0.3 extra cells in the anterior pharynx compared to 11.9 extra cells for egl-1(n1084 n3082)).
MD5017 ced-3(dx228[ced-3::mNeonGreen]) IV. C. elegans mNeonGreen tag inserted at C-terminus of endogenous ced-3 locus. Generated in N2 background. Reference: Lambie EJ, et al. Cell Death Differ. 2025 Aug 27. doi: 10.1038/s41418-025-01567-8. PMID: 40866673.
MD5018 ced-4(dx226[ced-4::mNeonGreen]) III. C. elegans mNeonGreen tag inserted at C-terminus of endogenous ced-4 locus. Generated in N2 background. Reference: Lambie EJ, et al. Cell Death Differ. 2025 Aug 27. doi: 10.1038/s41418-025-01567-8. PMID: 40866673.
MD5019 ced-9(dx236[mNeonGreen::ced-9]) III. C. elegans mNeonGreen tag inserted at N-terminus of endogenous ced-9 locus. Generated in N2 background. Reference: Lambie EJ, et al. Cell Death Differ. 2025 Aug 27. doi: 10.1038/s41418-025-01567-8. PMID: 40866673. .
