DpyUnc.

ad810 is homozygous lethal. ad810/+ is Egl and it suppresses gpb-2. gpb-2 phenotype is rather subtle: they are slightly starved, slightly longer than normal, and tend to be loopy in their movements (they make abnormally deep bends). Hets should be Egl and non-Eat. On most E. coli strains gpb-2 grows rather poorly, especially if the plates are older so that there is a thick and tough lawn. On such plates there will be a lot of gpb-2 larval arrest, and those that don't arrest will grow slowly. The hets should easily outgrow the gpb-2 homozygotes. [gpb-2 is also hypersensitive to the drug arecoline: they won't grow on 5 mM. The hets will grow even better than WT on 5 mM arecoline.] gpb-2(ad541) previously called eat-11(ad541).

Suppressor of gpb-2 (a.k.a. eat-11) arecoline hypersensitivity. Unc. Egl.

Roller. Unc. Vulvaless. Throws males. sc8 previously called rol-4(sc8).

uonEx1 [unc-54::alpha-synuclein::CFP + unc-54::alpha-synuclein::YFP(Venus)]. Pick fluorescent animals to maintain. No additional transformation marker was included in the array. uonEx1 also known as SC+SV in reference publications. Reduced lifespan (25-35% lower) and reduced pharyngeal pumping rate compared to N2. Novel transgenic strain for monitoring the influence of genetic and/or environmental factors on the extent of alpha-synuclein aggregation using FRET signals. Because the two fusion proteins are separate, FRET is only possible when synuclein aggregation brings a CFP tag very close to a YFP tag within an aggregate. We suggest using this strain in conjunction with the positive control (high FRET) strain DDP2 or with strain NL5901 which shows opposite changes in FRET. References: Nagarajan A, et al. CNS Neurol Disord Drug Targets. 2015 Aug 21. Bodhicharla R, et al. CNS Neurol Disord Drug Targets. 2012 Dec;11(8):965-75.

uonEx2 [unc-54::CFP::YFP(Venus)]. No additional transformation marker was included in the array. uonEx2 also known as CV in reference publications. Lifespan and pharyngeal pumping rates are similar to N2. This is a high-FRET positive control strain for use in conjunction with DDP1. Because the CFP and YFP protein sequences are covalently fused together (and show little evidence of cleavage), FRET should be high and largely invariant since both fluorescent moieties are always in close proximity.
