Abstract
Colicin E2 was partially purified from Escherichia coli W3110. This preparation was remarkably stabilized by bovine serum albumin in a solution at neutral pH, as shown by dilution experiments and tests on heat stability of colicin. One killing unit of colicin E2 was estimated to correspond to one molecule of colicin E2, on the assumption of a molecular weight of 60,000.
摘要
大肠杆菌素E2从大肠杆菌W3110中部分纯化得到。如稀释实验和大肠杆菌素热稳定性测试所示，在中性pH溶液中，该制剂在牛血清白蛋白的作用下能显著稳定。假设分子量为60,000，估计一个大肠杆菌素E2杀伤单位对应一个大肠杆菌素E2分子。
