Giardia lamblia -- a model organism for eukaryotic cell differentiation.

abstract：:Methods for in vivo monitoring of redox changes in different cellular compartments have been developed in recent years, and are mostly based on redox-sensitive variants of the green fluorescent protein (GFP). However, due to the thermodynamic stability of the introduced reactive disulfide bond, these sensors are limit...
