The Eagle Biosciences 8-Isoprostane ELISA Assay Kit was utilized in a recent research project. This kit is part of our Oxidative Stress Assay Kit line which is a line of highly sensitive and specific assays used to detect a variety of samples in serum, plasma, tissue, urine, and saliva.

Effect of flavoring chemicals on free radical formation in electronic cigarette aerosols

Background

Flavoring chemicals, or flavorants, have been used in electronic cigarettes (e-cigarettes) since their inception; however, little is known about their toxicological effects. Free radicals present in e-cigarette aerosols have been shown to induce oxidative stress resulting in damage to proliferation, survival, and inflammation pathways in the cell. Aerosols generated from e-liquid solvents alone contain high levels of free radicals but few studies have looked at how these toxins are modulated by flavorants.

Conclusions

Our results suggest that flavoring agents play an important role in either enhancing or inhibiting the production of free radicals in flavored e-cigarette aerosols. This information is important for developing regulatory strategies aimed at reducing potential harm from e-cigarettes.
