Fig. 2. SDS-PAGE of three arteries (ALA, SA and DAA), the ostial muscle (OOM), and
the slow and fast skeletal muscles, shows bands identified as actin, myosin
and tropomyosin. The left-hand lane (MW) contains protein markers of known
molecular mass (in kDa). Labelled on the right are myosin heavy chain (MHC),
paramyosin (P1, 2), P75 in fast skeletal muscle, actin, tropomyosin (Tm), and
troponins T (TnT) and I (Tnl).
