Abstract— In cerebral myelin from man, ox, rabbit, guinea pig and chicken, the amounts of proteolipid protein, basic protein and the fraction of further protein components were found to be present in a fixed ratio of 5·0: 3·5: 2·0 by weight. The molecular weights of 25,000 and 35,000 as obtained for the basic protein and proteolipid protein might indicate that cerebral myelin contains one molecule of basic protein per molecule of proteolipid protein. This fixed ratio of protein components was found to be changed in myelin from the PNS and in cerebral myelin from rat and carp, with their exceptional basic proteins. Using the polyacrylamide-gel electrophoresis it was possible to demonstrate that a homogeneous structural protein (the Folch-Lees proteolipid protein) constitutes about 50 percent of the total amount of myelin proteins in all species studied. An attempt was made to correlate myelin protein and lipid patterns from various species.
