GFP tag inserted in endogenous unc-94 locus; specifically tags UNC-94A isoform. Green fluorescence is visible by compound microscopy as striations in body wall muscles, as elongated puncta in single-sarcomere (anal depressor, uterine, and vulval) muscles, as well as the cell bodies of two neurons. Not visible on fluorescent dissection microscopes. Modifcation of the endogenous myo-3 loci by the insertion of a trans-splicing ICR region and worm-optimized mCherry at region encoding the head-neck junction. Bright red fluorescence is visible as striations in body wall muscles and clusters in single-sarcomere (anal depressor, vuvla, uterine) muscles. Please contact Ryan Littlefield prior to publishing work using this strain.
