摘要: We generated a mutant of the red fluorescent protein drFP583. The (E5) changes its fluorescence from green to over time. rate color conversion is independent concentration and therefore can be used trace time-dependent expression. in vivo labeling with E5 measure expression heat shock-dependent promoter Caenorhabditis elegans Otx-2 developing Xenopus embryos. Thus, "fluorescent timer" that monitor both activation down-regulation target promoters on whole-organism scale.
