Ribosomes from Gram-positive and Gram-negative bacteria have been analysed for the presence of ribosomal protein S1 by three methods, sodium dodecyl sulfate polyacrylamide gel electrophoresis, immunoreaction with E. coli anti-S1 and chromatography on poly (U)-Sepharose. We observed that protein S1 is predominantly present in Gram-negative bacteria in comparison with Gram-positive bacteria. Exceptions are noted in both species.
已通过三种方法对革兰氏阳性菌和革兰氏阴性菌的核糖体进行了分析，以检测核糖体蛋白S1的存在，这三种方法分别是十二烷基硫酸钠聚丙烯酰胺凝胶电泳、与大肠杆菌抗S1的免疫反应以及在聚（U）-琼脂糖凝胶上的色谱分析。我们观察到，与革兰氏阳性菌相比，蛋白S1主要存在于革兰氏阴性菌中。在这两种菌中均发现了例外情况。
