丙种球蛋白制剂中的蛋白含量,《生物制品化学检定规程》一书中采用凯氏定氮法测定,操作费时费事。我们试用双缩脲法测定蛋白含量,操作简便快速,结果较准确。丙种球蛋白占总蛋白的含量测定,《生物制品化学检定规程》一书采用纸上电泳法,电泳时间需5～6小时,且分离图谱不清晰,拖尾现象严重。我们试用醋酸纤维薄膜分离,电泳时间仅需40～50分钟,且分离图谱清晰,无施 Protein content of gamma globulin preparations, “chemical products, chemical test procedures,” a book using Kjeldahl determination of the method, the operation time-consuming. We try biuret method for the determination of protein content, the operation is simple and quick, the result is more accurate. Gamma protein content of total protein determination, “Biological chemical products,” a book on the electrophoresis paper electrophoresis method, electrophoresis time of 5 to 6 hours, and the separation of the map is not clear, the phenomenon of severe tailing. We try acetate film separation, electrophoresis time only 40 to 50 minutes, and the separation of the map clear, non-Shi
