A Rapid Protocol for Integrating Extrachromosomal Arrays With High Transmission Rate into the <em>C. elegans</em> Genome

Abstract: Microinjecting DNA into the cytoplasm of the syncytial gonad of Caenorhabditis elegans is the main technique used to establish transgenic lines that exhibit partial and variable transmission rates of extrachromosomal arrays to the next generation. In addition, transgenic animals are mosaic and express the transgene in a variable number of cells. Extrachromosomal arrays can be integrated into the C. elegans genome using UV irradiation to establish nonmosaic transgenic strains with 100% transmission rate of the … Show more

“…ceh-17:: GCaMP6 was injected into N2 animals together with ceh-17::dsred (Suo et al, 2006) and lin-44::gfp (Murakami et al, 2001) as a coinjection marker. The resulting strain was subjected to UV irradiation to integrate the extrachromosomal array into the genome (Mariol et al, 2013). The strain carrying the integrated transgene was backcrossed to N2 animals three times and then crossed to CB4088 him-5.…”

“…Additionally, the following multi-copy integrated transgenes were used: adIs2122(lgg-1p::GFP::lgg-1 + rol-6 (su1006)) [102], bpIs151 (sqst-1p::sqst-1::GFP + unc-76(+)) [51], zcIs9 (P hsp-60 ::gfp::unc-54 3'UTR) [14], zcIs13 (P hsp-6 ::gfp::unc-54 3'UTR) [14], zcIs18 (P ges-1 ::gfp(cyt)) [103], bcIs79 (P let-858:: gfp mt ::let-858 3'UTR + rol-6(su1006)), bcIs78 (P myo-3 ::gfp mt ::unc-54 3'UTR + rol-6(su1006)) [46]. The strains MOC92 bicIs10(hsp-1::tagRFP::unc-54 3'UTR) and MOC119 bicIs12(ttr-45p:: tagRFP::ttr-45 3'UTR) were generated in the Casanueva lab by gonadal microinjection of plasmids pMOC1 and pMOC2, respectively followed by genome integration via UV irradiation using a Stratagene UV Crosslinker (Stratalinker) [104]. The irradiation dose was 35mJ/cm 2 corresponding to Stratalinker power set up at 350.…”

“…Wild-type: (N2 Bristol); Transgenic strains: NM2415 (lin-15B(n765); jsIs68[Prab-3::GFP::rab-3 + lin-15(+)]), LC108 (vIs69 [pCFJ90(Pmyo-2::mCherry + Punc-119::sid-1)]) OH441(punc-119::GFP); Mutant strains: RB652 (puf-7(ok361)) and JK3231(puf-8(q725)) were obtained from the Caenorhabditis Genetics Center (University of Minnesota, Minneapolis, MN). The transgenic strain CQ574 (lin-15B(n765); jsIs682 ]; wqIs3 [Prab3::mCherry]) was generated by UV integration (Mariol et al, 2013) of NM2415 (lin-15B(n765); jsIs68[Prab-3::GFP::rab-3 + lin-15(+)]) animals microinjected with a Prab3::mCherry transgenic construct, followed by 3 rounds of outcrossing with wild-type (N2 Bristol) worms.…”
