Live-cell metabolic analysis of oligodendroglia isolated from postnatal mouse brain and spinal cord

This protocol describes isolation and live-cell metabolic analysis of O4+ oligodendroglia from brain and spinal cord of postnatal mice. We have optimized existing protocols for O4+ isolation from neonatal brain and expanded the protocol to include isolation of highly viable oligodendroglia from spinal cords of postnatal mice up to 18 days of age. Isolated oligodendroglia can be used in multiple downstream analyses, and here we describe an optimized real-time metabolic assay using Agilent Seahorse Analyzer to measure mitochondrial respiration. For complete details on the use and execution of this protocol, please refer to Khandker et al. (2022).
