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