Longitudinal variation in muscle protein expression and contraction kinetics of largemouth bass axial muscle

Summary The present study investigates muscle protein caudal muscle had a lower total parvalbumin content than expression in largemouth bass Micropterus salmoides rostral muscle. Since troponin T and parvalbumin have through intra- and intermyomeric comparisons of white been implicated in the regulation of skeletal muscle muscle. Using denaturing SDS-polyacrylamide gel kinetics, longitudinal variation in muscle contraction electrophoresis, muscle protein expression in the arm and kinetics was predicted. Subsequent experiments revealed cone regions of sequential myomeres was compared for that bass rostral white muscle showed faster rates of three bass. Low percentage (4.75 %) polyacrylamide-SDS activation and relaxation than more caudal muscle, as has gels and cyanogen bromide (CNBr) peptide mapping been observed in white muscle of other fish species. revealed no obvious intramyomeric differences between Rostral–caudal variations in white muscle protein the myosin heavy chains of the arm and cone regions. composition and contractile properties are predicted to Electrophoresis of myofibrils and muscle homogenates on affect patterns of power production during fast, unsteady higher percentage gels also failed to demonstrate any swimming. significant differences between arm and cone regions in either the myosin light chains or any of the major
