An enhanced luminescent or luminometric assay, especially immunoassay, having a luminescent reaction between a peroxidase enzyme, an oxidant, a 6-hydroxybenzothiazole and a chemiluminescent 2,3-dihydro-1,4-phthalazinedione. The preferred materials are horse radish peroxidase as the enzyme, hydrogen peroxide as the oxidant, 6-hydroxybenzothiazole, 2-cyano-6-hydroxybenzothiazole or firefly luciferin as the benzothiazole 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.
一种增强型发光或荧光测定法,特别是免疫测定法,它在过氧化物酶、氧化剂、6-羟基苯并噻唑和化学发光的 2,3-二氢-1,4-酞嗪二酮之间发生发光反应。 首选材料是作为酶的萝卜过氧化物酶,作为氧化剂的过氧化氢,作为苯并噻唑的 6-羟基苯并噻唑、2-氰基-6-羟基苯并噻唑或萤火虫荧光素,以及作为酞嗪二酮的发光酚或隔离酚。 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。
