The microscope was equipped with a CO2 and temperature controllable incubator (Life Imaging Services, 37C). Photoactivation is prevented by protonation of the aniline groups and is therefore highest at pH values above pH=6 as revealed by measuring the maximal absorbance at 646nm reached directly after activation (Amax).
