Detection of Nanoparticle-Mediated Change in Mitochondrial Membrane Potential in T Cells Using JC-1 Dye.

Abstract

Alterations in mitochondrial membrane potential are associated with the generation of reactive oxygen species and cell death. While eliminating cancer cells is beneficial for cancer therapy, cytotoxicity to healthy cells may limit the therapeutic applications of mitochondria-damaging nanoparticles. Due to the critical role mitochondria play in cell viability and function, it is important to detect such alterations when studying nanomaterials for therapeutic applications. The protocol described herein utilizes JC-1 dye to detect nanoparticle-mediated changes in mitochondrial membrane potential and is intended to support mechanistic immunotoxicology studies.
