Experientia Aims and scope Submit manuscript

Summary

The Ca++-ATPase system of sarcoplasmic reticulum (SR) was resolved into several subunits by isoelectric focusing and isotachophoresis in acrylamide gels. The results obtained support the concept that the ATPase system of SR is oligomeric forming a tetramer of 100,000 mol.wt subunits.
