## 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
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
