Isolation of two proteolipids from rabbit skeletal muscle sarcoplasmic reticulum.
We have isolated two proteolipids from rabbit skeletal muscle sarcoplasmic reticulum by chromatography on columns of Sepharose CL-6B and Sephadex LH-60. One, PL-II, is identical to the proteolipid previously obtained by others using organic solvent extraction. The other, PL-I, has an amino acid composition very similar to those of proteolipids we previously isolated from canine cardiac SR and lamb kidney (Na,K)-ATPase.
