Fig. 7. Biochemical properties of the mutant sciatic nerves. Western blot analysis of Mat1, Cdk7, p44, CNPase, and 18.5, 17 and 14 kDa myelin basic protein (MBP) isoforms from whole sciatic nerve protein lysates from control (control 1; Mat1flox/-, control 2; Mat1flox/+;KCN) and mutant (Mat1flox/-;KCN) animals at P70.
