Firefly oxyluciferin (2-(6'-hydroxybenzothiazolyl)-4-hydroxythiazole) was c
hemically synthesized and characterized by means of C-13 and H-1 NMR, UV-vi
s spectrometry and RP-HPLC using different pH elution conditions. One of th
e chromatographic peaks observed in luciferase-catalyzed reaction mixtures
was identified Lis corresponding to oxyluciferin. (C) 2001 Elsevier Science
