Quantitative determination of the full switching cycle of photochromic fluorescent proteins

Abstract

In this study, we develop a general analytical model of the photochromism of fluorescent proteins and apply it to spectroscopic measurements performed on six different labels. Our approach provides quantitative explanations for phenomena such as the existence of positive and negative switching, limitations in the photochromism contrast, and the fact that initial switching cycles may differ from subsequent ones. It also allows us to perform the very first measurement of all four isomerization quantum yields involved in the switching process.
