A radioconjugate consisting of the 7 amino acid peptide sequence ASYNYDA (GI heptapeptide) and labeled with the fluorescent dye fluorescein isothiocyanate (5-FITC), with potential imaging activity. Upon topical application to the esophageal mucosa using a spray, the heptapeptide moiety of 5-FITC-labeled GI-heptapeptide binds to abnormal cells in the esophagus; the FITC moiety allows for imaging with white light and the area of interest for biopsies can then be visualized. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
