Blood-based biomarkers for neurodegenerative diseases are essential for implementing large-scale clinical studies. A reliable and validated blood test should require a small sample volume as well as be a less invasive sampling method, affordable, and reproducible. This paper demonstrates that high-throughput capillary electrophoresis immunoassay satisfies criteria for potential biomarker development.

Preparation of mitochondria-enriched samples from previously frozen archived solid tissues allowed the investigators to perform both functional and analytical assessments of mitochondria in various experimental modalities. This study demonstrates how to prepare mitochondria-enriched preparations from frozen heart tissue and perform analytical assessments of mitochondria.
