above were resuspended in 150 μL of PBS after each experiment
and dropped onto an uncoated microslide with coverslip (MatTek Corp.).
Confocal fluorescence microscopy (CFM) experiments were performed
using a Zeiss LSM 510 META NLO two-photon laser scanning confocal
microscope system, operating at a 488 nm excitation wavelength and
at 527 ± 23 nm detecting emission wavelength using a 505–550
nm bandpass filter. Images were captured using a C-Apochromat 63x/1.2 water (corr) objective. Images for conjugate
camera mode with a filter set of 350 ± 25 nm excitation wavelength
and 420 nm long pass emission wavelength. Acquired data were analyzed
using LSM 510 Meta software.
