double-stranded DNA are described. Endcap diols were converted into DMTr protected phosphoramidites and incorporated between nucleotides 4 and 5 of a self-complementary octamer. The stabilizing effect of the endcaps on duplex DNA was determined by Tm experiments on the self-complementary octamer.
                                    描述了用于共价连接平末端双链DNA的3'和5'羟基的端帽的合成。封端二醇被转化为
DMTr保护的亚
磷酰胺,并掺入到自互补八聚体的核苷酸4和5之间。通过Tm实验对自互补八聚体测定端帽对双链DNA的稳定作用。
