Luminescent immunoassays combine great sensitivity with broad dynamic range. One of the more effective luminescent indicators is Luminol, which, with proper enhancers, gives a bright and stable light emission. Figure 1. Enhanced Luminol Reaction Luminol (3-aminophthal hydrazide) was first synthesized as a chemiluminescent substrate in 1928. Unfortunately, the...
