Ribosomal subunits were prepared from rat liver and skeletal muscle after incubation with puromycin and treatment at low concentrations of Mg(2+). After isolation the resulting subunits could be recombined and the particles effected the synthesis of polyphenylalanine in the presence of polyuridylic acid. Hybrid particles formed from subunits of liver and muscle respectively were also active. The homogeneity of the isolated subunits was checked by polyacrylamide-gel-agarose electrophoresis. The method is shown to be a reliable and comparatively simple way of preparing active ribosomal subunits from skeletal muscle.
用嘌呤霉素孵育并在低浓度镁离子(Mg²⁺)条件下处理后,从大鼠肝脏和骨骼肌中制备核糖体亚基。分离后,所得的亚基可以重新组合,并且这些颗粒在多聚尿苷酸存在的情况下能够合成聚苯丙氨酸。分别由肝脏和肌肉的亚基形成的杂交颗粒也具有活性。通过聚丙烯酰胺 - 琼脂糖凝胶电泳检查分离的亚基的均一性。结果表明,该方法是从骨骼肌制备活性核糖体亚基的一种可靠且相对简单的方法。
