Proportions of soleus fibers staining positively for specific fast and slow MHC isoforms in wild-type and MCK* transgenic mice. No fibers stained positively for MHC-IIb with mAb BF-F3, thus antibody RT-D9 which is specific for MHC-IIx and MHC-IIb indicated the presence of MHC-IIx. No significant differences in fiber proportions of the soleus were found between wild-type and MCK-CN* mice.
