WebThe increased stability of myofibrils occurring in the transition from nascent to mature myofibril assembly indicates the importance of dynamics and selective destruction in the muscle myosin II proteins for the remodeling of nascent to mature myofibrils. WebMyofibrils were frozen on grids by plunge-freezing using a Vitrobot. Generally, 2 μl of myofibril suspension was applied onto the glow-discharged carbon side of Quantifoil R 1.2/1.3 Cu 200 grids. After a 60-s incubation at 13°C, the grids were blotted from the opposite side of the carbon layer for 15 s before plunging into liquid ethane. ...
