standard sequencing enzymes T7 DNA polymerase, sequenase version 2.0, Thermus aquaticus DNA polymerase, and Thermus thermophilus DNA polymerase. Both radioactive and fluorescent sequencing methods were applied successfully to the 3′-amino-modified terminators. Investigations in view of using these chain terminators according to Sanger's sequencing method for fluorescence labeling were done.
我们描述了由相应的3'-叠氮基衍生物制备的四个含有3'-氨基的DNA碱基的修饰核苷三磷酸的合成。引入三磷酸酯并随后将N 3还原为NH 2基团直接导致了目标分子6a–d。此外,事实证明3'-氨基-2',3'-二脱氧核苷5'-三磷酸酯是通过标准测序酶T7 DNA聚合酶,sequenase 2.0版,Thermus aquaticus DNA聚合酶和Thermus催化的DNA酶促合成的有效抑制剂。嗜热菌DNA聚合酶。放射性和荧光测序方法均成功应用于3'-氨基修饰的终止子。考虑到根据Sanger的测序方法使用这些链终止剂进行荧光标记的研究。
