Disclosed herein are compositions and methods for stabilizing a benzothiazole luciferin analog such as D-luciferin and 6-amino-D-luciferin. The compositions may include the benzothiazole luciferin analog, a thionucleobase compound of formula (I), and a liquid medium, in which the thionucleobase is present in an amount effective to stabilize the luminogenic composition against decomposition. The methods provided herein may stabilize the benzothiazole luciferin analog against decomposition by contacting the benzothiazole luciferin analog with an effective amount of the thionucleobase compound in the presence of a liquid medium. Also provided herein is a kit containing the composition.
