The non-ionic detergent Triton X-100 solubilizes most of the protein and phospholipid from the sarcoplasmic reticulum of rabbit skeletal muscle. The calcium dependent ATPase of the sarcoplasmic reticulum is found in the soluble fraction whereas the basic ATPase activity remains insoluble in Triton X-100. Analytical ultracentrifugation and disc electrophoresis indicate that the solubilized material consists of particles having a molecular weight of approximately 80,000 daltons. These particles have a strong tendency to aggregate.
