Abstract

Visible light is emitted on oxidation of 0.00001 , µg/ml (2 x 10-11M) of Cypridina luciferin with 0.01 mg/ml of luciferase protein, or with 1 µg/ml of luciferin with 0.0000001 µg/ml (2 x 10-15M) of luciferase. Data on yields indicate the average content of luciferin and luciferase to be, at best, about 1 µg of each in a single living organism.
