title: Preparation of highly purified mitochondria of Neurospora crassa on a Percoll gradient.
abstract: Mitochondria isolated from Neurospora crassa were purified by centrifugation in a Percoll density gradient. Enzyme activities and cytochrome differential spectra revealed a high purity of the mitochondria. As compared with a crude mitochondrial fraction the purified mitochondria exhibited a high respiratory activity and a fine ADP/O ratio. Electrophoresis of nucleic acids demonstrated the absence of cytoplasmic rRNA.
