An enhanced luminescent or luminometric assay, especially immunoassay, having a luminescent reaction between a peroxidase enzyme, an oxidant, a chemiluminescent 2,3 -. dihydro- 1,4 - phthalazinedione and a sensitivity enhancer of general formula I,
The preferred materials are horse radish peroxidase as the enzyme, hydrogen peroxide as the oxidant, one of 4 - iodophenol, 4 - phenylphenol or 2 - chloro - 4 - phenylphenol as the enhancer and either luminol or isoluminol as the phthalazinedione. In a particularly preferred embodiment the horse radish peroxidase is coupled to an antibody to the substance to be assayed and thereby acts as the assay label in an immunoassay.
一种增强的发光或荧光测定法,特别是免疫测定法,它在过氧化物酶、氧化剂、化学发光的 2,3 - 二氢- 1,4 - 酞嗪二酮和通式 I 的灵敏度增强剂之间发生发光反应。 在一个特别优选的实施方案中,萝卜过氧化物酶与待测物质的抗体偶联,从而在免疫测定中作为测定标记。
