[Production of glycerinated models of muscle fibers with phosphorylated myosin light chains].
A simple method for obtaining glycerinated muscle fibres of m. psoas of rabbit containing regulatory myosin light chains (LC2) of different levels of phosphorylation. The glycerination conditions stimulated endogenic kinase LC2 or phosphatase LC2. Glycerinated muscle fibres contained phosphorylated and dephosphorylated (levels of phosphorylation are 95 +/- 5%, and 5 +/- 5%, respectively) LC2 of myosin. To determine the level of phosphorylation the method of polyacrylamide gel electrophoresis in 8 M urea was modified.
