The Cypridina luciferin analog, 2-methyl-6-phenyl-3,7-dihydroimidazo[1,2-a]pyrazin-3-one (CLA), in Hanks' balanced salt solution, emitted a weak luminescence which was not affected by superoxide dismutase or catalase and was not augmented by resting human granulocytes. In contrast, activated granulo

## Abstract The chemiluminescence of the __Cypridina__ luciferin analogue, 2‐methyl‐6‐(p‐methoxyphenyl)‐3,7‐dihydroimidazo[1,2‐a]pyrazin‐3‐one (MCLA) was observed at 462nm in the presence of horseradish peroxidase (HRP) and the total spectrum of light emitted was found to depend linearly on HRP con
