Fig. 2From: Rapid detection of papillary thyroid carcinoma by fluorescence imaging using a γ-glutamyltranspeptidase-specific probe: a pilot studyRepresentative figure of PTC exhibited green fluorescence of HMRG upon reaction with GGT. a White-light image of thyroid tissue, normal (left) and carcinoma (right), taken under incandescent light without gGlu-HMRG. b-h Images captured before and 3 s, 30 s, 1, 3, 5 and 10 min after probe application. Green fluorescence signals were observed after 3 sBack to article page
