Molecular weight studies of canine cardiac myosins

摘要: Only recently were conditions developed for determining accurately the molecular weight of myosin [ 1,2] . Conditions selective obtaining in a monomeric form used such as, analyses at low protein concentration ( 0.3 M KCl) [l-3] Using these rabbit skeletal muscle was 458 000 [l] and 468 [2] , weights considerably lower than that reported earlier myosins [4,5] Optimal following studies determination canine cardiac left right ventricular myosins. Earlier on obtained from dog heart described as 225 [6] 758 [7].
