Strains contributed by this laboratory

Strain Genotype Species Description
KWN117 pha-1(e2123) III; him-5(e1490) V; rnyEx60. C. elegans rnyEx60 [pELA2 (vha-6p:::vha-6::mCherry) + myo-3p::GFP + pCL1 (pha-1+)]. Labels apical intestinal membrane. Reference: Allman et al. (2009) Am J Physiol Cell 297:C1071-81.
KWN190 pha-1(e2123) III; him-5(e1490) V; rnyEx109. C. elegans rnyEx109 [nhx-2p::D3cpv + pha-1(+)]. Maintain at 20-25C to select for array. KWN190 strain expresses the FRET-based calcium indicator protein D3cpv throughout the cytoplasm of intestinal cells. Dual emission ratio imaging (ex. 435, em. 480/535-nm) can be used to measure intestinal calcium and, although the FRET pair is CFP/YFP, intestinal D3cpv fluorescence is observable under standard GFP filter sets. The D3cpv biosensor has the advantages of being relatively pH-insensitive and not interfering with endogenous calmodulin signaling. References: Am J Physiol Cell Physiol. 301:C1389-1403.

KWN246 pha-1(e2123) III; rnyEx133. C. elegans rnyEx133 [opt-2p:::opt-2(aa1-412)::GFP) + pha-1(+)]. Maintain at 25C to select for animal carrying the array. Labels apical intestinal membrane. Reference: Nehrke (2003) 278(45):44657-66.
KWN26 pha-1(e2123) III; rnyEx6. C. elegans rnyEx6 [nhx-2p::pHluorin + pha-1(+)]. Maintain at 20-25C to select for array. KWN26 strain expresses the pH-sensitive GFP variant pHluorin throughout the cytoplasm of intestinal cells. Dual excitation ratio imaging (ex. 410/470, em. 435-nm) can be used to measure intestinal pH and intestinal pHluorin fluorescence is observable under standard GFP filter sets.
