Mitochondrial function after global cardiac ischemia and reperfusion: Influences of organelle isolation protocols

Dog hearts were made globally ischemic for 1 hr at normothermia, at 28°C, or at normothermia after perfusion with a hyperkalemic cardioplegia solution. After 1 hr of reperfusion mitochondria were isolated from each heart using three protocols involving: processing (homogenization and centrifugation) exclusively in KCl, Tris-EDTA plus albumin (KEA) solution; homogenizing in KEA but washing mitochondria in EDTA-depleted media (KA); or processing exclusively in EDTA-free medium.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/41745/1/395_2005_Article_BF01907770.pd
