**CDr20** works both in vitro cell culture and on brain slice. In mouse embryo, **CDr20** penetrated into brain tissue and live microglia was fluorescently stained. Through iv injection, **CDr20** was introduced to Alzheimer mouse brain and the microglia could be in situ imaged by two photon fluorescence microscope.
