A dual enzyme chemiluminescent substrate formulation useful for the independent or simultaneous analysis of the enzymes is disclosed, the formulation includes, as one substrate component, dihydrophthalazinedione, such as luminol or isoluminol, and a peroxide source and, as the other substrate component, a 1,2-dioxetane. The formulation further includes a polymeric quaternary onium salt as an isolating agent to defeat adverse interactions between the substrate pairs.
