Figure Lengend Snippet: (A) Immunofluorescence images showing localization of mito-sensors tagged to a YFP (Green) with endogenous TOM20 staining (red) and the superposition of both acquisitions with Dapi (blue). (B) Merged images showing localization of mito-sensors tagged to a Nluc (Green) with Mito Tracker Red CMX Ros staining (Red). (C) Schematic representation of localization sensors in different compartments. (D, E, F) BRET values represent the proximity between -MX-Nluc, ATP5F1C-Nluc, and OTC-Nluc, respectively, and localization sensors (YFP). n =5. (G) Schematic representation of the localization of the Sirtuins and MX loc-biosensor in different compartments. (G) BRET values represent the proximity between MX-Nluc, MX-YFP, and sirtuins (YFP), n = 4
Article Snippet: TOM20-YFP(Nluc) fusion proteins were obtained by fusing the TOM20 coding region (Addgene # 55146) in its c-terminus to YFP or Nluc.
Techniques: Immunofluorescence, Staining
