Interaction studies of γ-secretase subunits in Arabidopsis thaliana protoplasts. Simultaneous expression of γ-secretase subunits showed their colocalization. Fluorescent signal of particular subunit fused with GFP is presented in green and fused with RFP in red. Colocalization of γ-secretase subunits is shown in merged channel (yellow). Fluorescence lifetime measurements are presented on most-right panel and certain lifetime values are presented in white boxes (Tamp). χ2 near 1 indicates good quality of fitting. Bar, 10 µm.
