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.
