Fig. 7. Analysis of myosin heavy chain (MHC), actin and P75 expression in slow
fibers by RT-PCR. Experimental arrangement is as in
Fig. 6. Different slow fibers
[distal cutter (lane a), ventral cutter (lane b), crusher (lane c), lateral
superficial extensor (lane d)] predominantly expressed S1 MHC and
actin. The distal cutter (lane a) shows low amounts of fast MHC product. Actin
expression (B) with this method appears to be higher than S1 MHC
expression (A). (Inverse images of ethidium bromide-stained gels.)
