Optimized protocol for quantification of mitochondrial non-heme and heme iron content in mouse tissues and cultured cells

Abstract

Summary: Impaired mitochondrial iron metabolism is associated with aging and a variety of diseases, and there is a growing need to accurately quantify mitochondrial iron levels. This protocol provides an optimized method for evaluating non-heme and heme iron in mitochondrial and cytosolic fractions of tissues and cultured cells. Our protocol consists of three steps: sample fractionation, non-heme iron measurement, and heme iron measurement.For complete details on the use and execution of this protocol, please refer to Sato et al. (2022).1 : Publisher’s note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics.
