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...

The HT 8-oxo-dG ELISAs are plate-based immunoassays designed for detecting and quantifying 8-hydroxy-2’-deoxyguanosine (8-oxo-dG). 8-oxo-dG is a frequently used biomarker of oxidative DNA damage and oxidative stress. Reactive oxygen and nitrogen species generated by normal metabolic processes and a variety of environmental factors cause the hydroxylation of guanosine at the N7-C8 bond. 8-oxo-dG...
