Notes:
The luminescence of obelin is initiated by NaOCl in a reaction mixture containing no calcium. The addition of Mn2+ enhances the light emission 〉300-fold. Sodium azide and histidine, as singlet oxygen quenchers, inhibit NaOCl-activated obelin luminescence in the presence or absence of Mn2+. This suggests that the addition of NaOCI to the mixture causes singlet oxygen formation (stimulated by Mn2+ ions), and singlet oxygen initiates the light-emitting reaction.
