Total RNA was extracted from whole mystacial pads of mouse, rat, and guinea pig and analyzed by RT-PCR. The fluorescence intensities of the ethidium bromide-stained PCR products as observed on agarose gel electrophoresis were used to compare the MyHC isoform mRNA levels in different species. nd, Not detected; ?, no appropriate primers for these mRNAs were available.
