Abstract : Microorganisms and selected proteinaceous substances were directly tagged with fluorescein isothiocyanate. This approach suggested a possible application for detection of extraterrestrial life. A stable and apparently specific linkage was formed with protein, although nonprotein substances were readily destained. Substances such as soil and atmospheric debris did not exhibit any significant affinity for the dye.
