Neurochemical and morphological studies on the myelin of peripheral nervous system from Shiverer mutant mice: absence of basic proteins common to central nervous system.

Shiverer mouse is characterized by poor lamella formation and absence of major dense line in the CNS myelin. PNS of the Shiverer was normal with regard to myelin lamellar formation, immunohistochemical staining of the Schwann cells by S-100 protein, and the activity of 2',3'-cyclic nucleotide 3'-phosphohydrolase. Analysis of the purified myelin by SDS-polyacrylamide gel electrophoresis revealed that P1 and Pr, which are common to BP in CNS, and PM protein were missing, while P0 and P2 proteins were of the same level as the control.
