Actin protein (rabbit skeletal muscle, >95% pure)肌动蛋白（兔骨骼肌，>95%纯）

Material
Actin protein has been purified from rabbit skeletal muscle. AKL99 actin is greater than 99% pure and AKL95 is greater than 95% pure. Muscle actin has an approximate molecular weight of 43 kDa. Rabbit muscle actin is supplied as a white lyophilized powder. The lyophilized protein when stored desiccated to <10% humidity at 4°C is stable for 6 months. When re constituted in distilled water to 10 mg/ml, the protein is in the following buffer: 5 mM Tris-HCl pH 8.0, 0.2 mM CaCl2, 0.2 mM ATP, 5% sucrose, and 1% dextran.
