barry w. hicks and a team of well-practiced experimentalists demonstrate the power and the versatility of the green fluorescent protein (gfp) marker with a cutting-edge collection of readily reproducible gfp techniques. these include methods for detecting and imaging gfp (fret, bret, and whole-body imaging); for using gfp to create and select for transgenic organisms, for its use as a biosensor; and for studying viruses. a valuable companion cd-rom displays many color figures and videos from over half the chapters.
