etyEx106 [sra-6p::Cx36::YFP + flp-18p::Cx36::mCherry + unc-122p::GFP]. Pick animals with GFP+ coelomocytes to maintain. Artificial gap-junction between ASH and AVA. Reference: Pechuk V., et al. 2022, Current Biology 32, 1–14. https://doi.org/10.1016/j.cub.2022.08.038

GFP tag inserted at the 3' end of the endogenous daf-16 gene locus by CRISPR/Cas9 engineering. The GFP fusion tag does not interfere with the function of DAF-16 protein. DAF-16::GFP is expressed ubiquitously in most or all somatic tissues, including neurons, intestine, body wall muscles, and hypodermis, and also in the germ cells and oocytes. Reference: Zhang Y, et al. BioRxiv. 2021 Aug 2. 2007.2031.454567. https://doi.org/10.1101/2021.07.31.454567.

Nuclear Ultrabright GFP::mNeonGreen Fluorescent protein (NuGFP) tag inserted downstream of the endogenous daf-2 gene locus by CRISPR/Cas9 engineering. NuGFP cassette is composed of an intercistronic region (ICR) from the C. elegans SL2-type operon, a SV40 nuclear localization sequence (NLS), the coding sequence of GFP, the coding sequence of mNeonGreen, and egl-13 NLS. The expression of NuGFP is tied to that of the endogenous daf-2, but after trans-splicing, the NuGFP protein is synthesized independently of DAF-2. This high-sensitivity daf-2 expression reporter was readily detectable in most C. elegans cells throughout development and adulthood. Reference: Zhang Y, et al.
