Table 2. Myosin heavy chain mRNA composition in extraocular muscles during postnatal development
Myosin heavy chain (MHC) mRNA composition in extraocular muscles during postnatal development. Three competitive PCRs were performed on cDNA of each muscle. Gels were scanned once and the peaks were selected three times. Values are means±SD.
