CesiumChloridePurificationofT7
SummaryCleaner stocks of T7 that concentrates and purifies T7 bacteriophage.ProtocolGrow 100mL of permissive cells to a density of 108 to 109 cells/ml at 30°C in a rotary shaking water bath. Inoculate the cells with a drop from a master phage stock. Continue to shake cells in the water bath at 30°C until culture clarifies. Be careful not to let culture sit for long (>15 minutes) after culture clarif......阅读全文

T7－DNA聚合酶测序技术
一、概述T7 DNA聚合酶最初具有5'→3'聚合酶活性以及单链和双链3'→5'外切酶活性。当T7 DNA聚合酶用适当方法处理后，可使3'→5'外切酶活力明显下降。改造后的T7 DNA聚合酶又称T7测序酶。使用T7测序酶得到的测序数据具有在每个碱
