Large Scale Preparation of Liver Mitochondria with the Waring Blendor.

Abstract
A method is descr. for prepn. of mitochondria from 50 to 100 g. of liver. The tissue is pulped in a special tissue press and homogenized in isotonic sucrose at reduced motor speed for a short time in the Waring blendor. The mitochondria are isolated by differential centrifugation from isotonic sucrose. The ATP-ase, fatty acid oxidase, and succinoxidase activities of these prepns. were shown to be similar to those of mitochondria prepared with a pestle type homogenizer.
