What are examples of chemiluminescent substrates?

Examples of chemiluminescent substrates used with horseradish peroxidase (HRP) include luminol and acridan-based reagents. Alkaline phosphatase can utilize chemiluminescent substrates such as 4-methylumbelliferyl phosphate (4-MUP) or adamantyl 1,2-dioxetane aryl phosphate (AMPPD). Additionally, luciferase enzymes trigger light emission by oxidizing luciferins. Common chemiluminescent substrates for luciferase include luciferin and coelenterazine.
