Improved FRAP Measurements on Biofilms [PDF]

open access: yesBiophysical Journal, 2019
ABSTRACT We expand the standard FRAP model introduced by Axelrod et al. in 1976. Our goal is to capture some common artifacts observed in the fluorescence measurements obtained with a confocal laser scanning microscope (CLSM) in biofilms: 1) linear drift, 2) exponential decrease (due to bleaching during the measurements), 3) stochastic ...
