Yeast strains harboring a GFP-tag were grown at 25°C to early log phase (OD600 0.4–0.6) in selective SC medium. Fluorescence imaging was performed as described previously (Liu and Novick, 2014 (link)). In brief, images were acquired with a 100× oil immersion objective lens (Plan Apochromat 100×/1.4 NA oil DIC lens; Carl Zeiss) on a spinning disk confocal microscopy system (Yokogawa Electric Corporation), which includes a microscope (Observer Z1; Carl Zeiss) equipped with an electron multiplying charge-coupled device camera (QuantEM 512SC; Photometrics). Excitation of GFP or mCherry was achieved using 488-nm argon and 568-nm argon/krypton lasers, respectively. Images were analyzed using AxioVision software 4.8 (Carl Zeiss).
