BP600 C. elegans aff-1(tm2214) II. Show Description
A 1.2 kb deletion in aff-1 (C44B7.3) which introduce stop codon after alanine 47. AFF-1 is a type I membrane protein necessary and sufficient for specific cell fusion events during embryonic and larval development. Temperature sensitivity was not detected. At 20° the fusion of hyp5 in the embryo does not occur as well as anchor cell (AC) fusion, vulval cells fusion of the A and D rings and the terminal fusion between the seam cells late in L4. 6% L1 rod-like lethal and 0% embryonic lethal. Adults are completely Egl, and partially Unc, Pvl. In addition, only 2% of AC in the mutant worms undergo fusion. These animals give very low brood size (16 progeny per worm) and 3.4% of the worms are sterile. This strain gives very small brood size and hence grows slowly. Originally from Shohei Mitani, Tokyo Women's Medical College, Tokyo, Japan.

BRC546 C. elegans antIs30 II; unc-119(ed9) III. Show Description
antIs30 [attP-f + Cbr-unc-119(+) + glh-2p::phiC31 + rol-6(partial) + myo-2p::GFP + attP-r] II. antIs30 was inserted into ttTi5605 on LG II using MosSCI. GFP expression in pharynx is very weak (as it is single copy) and is easiest to see during the L1-L3 stages. This strain contains a phiC31 docking site and can be used for precise single-copy integration of transgenes via recombination mediated cassette exchange. The docking site contains inverted phiC31-attP sites flanking phiC31 integrase expressed from the glh-2 germline promoter. Integration constructs need to have inverted phiC31-attB sites that flank the intended sequence to be inserted. Reference: Yang FJ, et al. "phiC31 integrase for recombination mediated single copy insertion and genome manipulation in C. elegans." Genetics 2021.
BRC566 C. elegans antIs31 II; unc-119(ed9) III. Show Description
antIs31 [attP-f + Cbr-unc-119(ant40) + glh-2p::phiC31 + rol-6(partial) + myo-2p::GFP + attP-r] II. Unc. antIS31 has been found to self-excise; check for GFP expression periodically to retain the insertion. GFP expression in pharynx is very weak (as it is in single copy) and is easiest to see during the L1-L3 stages. This strain contains a phiC31 docking site and can be used for precise single-copy integration of transgenes via recombination mediated cassette exchange. The docking site contains inverted phiC31-attP sites flanking phiC31 integrase expressed from the glh-2 germline promoter. Integration constructs need to have inverted phiC31-attB sites that flank the intended sequence to be inserted. antIs31 was derived by CRISPR/Cas9 knockout of Cbr-unc-119 in antIs30 creating ant40, a 691 bp deletion in Cbr-unc-119. Because antIs31 does not rescue unc-119(ed3), BRC566 facilitates the use of Unc-119 rescue as a selection marker for transgene insertions. Reference: Yang FJ, et al.

Pick WT with dim GFP+ in pharynx to maintain. mIs11 homozygotes will quickly overtake the population if not selected against. GFP expression in 4-cell embryos, pharyngeal muscle and gut. ieDf2 is a deficiency of zim-1, zim-2, zim-3, and him-8 generated by MosDel, resulting in single-copy insertion of a copy of the C. briggsae unc-119 gene on Chromosome IV. The deletion spans the sequences from the beginning of the zim-1 coding sequence through the ttTi22866 Mos1 insertion site.
