Abstract

Deoxyuridine triphosphate derivatives modified with pyrene was synthesized to functionalize DNA with fluorescent molecules based on the template DNA sequence. Incorporation of pyrene-labeled deoxyuridine triphosphates into DNA by DNA polymerase was investigated by using reverse-phase HPLC and polyacrylamide gel electrophoresis. The fluorescent properties of functionalized DNA were characterized by the steady-state fluorescence measurements.

芘标记的三磷酸脱氧尿苷的合成与表征。
以模板DNA序列为基础,合成了芘修饰的三磷酸脱氧尿嘧啶衍生物,用荧光分子对DNA进行功能化。采用反相高效液相色谱法和聚丙烯酰胺凝胶电泳研究了DNA聚合酶将芘标记的脱氧尿苷三磷酸并入DNA。通过稳态荧光测量表征了功能化DNA的荧光特性。
