An EGFP-chimera of a GPI-anchored was expressed in HEK293 cells. The distribution of the protein in a membrane of living cells was imaged using Alba FLIM™. Cells were plated on a glass-bottom 35 mm Petri dish, kept in medium (HEPES buffer) and imaged at room temperature. Images were acquired using Alba FLIM™ equipped with the piezo-controlled stage using single photon excitation.
The Z-stack was acquired with 2-photon excitation at 920 nm. Images of 256x256 pixels were acquired with an integration time of 0.7 ms.
