DNA Polymerase Profiling

We report a simple homogeneous fluorescence assay for quantification of DNA polymerase function in high throughput. The fluorescence signal is generated by the DNA polymerase triggering opening of a molecular beacon extension of the template

The Polymerase Chain Reaction (PCR)

. Did He Really Invent PCR?　　• The basic principle of replicating a piece of DNA using two primers had already been described by Gobind Khorana in 1971:– Kleppe et al. (1971) J. Mol. Biol. 56, 341-346.　　• Progress was limited by primer synthesis and polymerase

DNA多聚酶DNA polymerase

能催化从四种5′-脱氧核苷三磷酸游离出焦磷酸而使DNA进行聚合反应的酶。EC2.7.7.7.。必须以DNA为模板，合成的DNA与模板具有互补的碱基排列（碱基互补性）。是与DNA复制和修复有关的重要的酶，虽可从许多组织分离出来，但对大肠杆菌的这种酶的研究较为先进。康伯格（A.Kornberg，1958）最初从大肠杆菌将此酶纯化，并弄清了其结构和特异性，但以后经过分子遗传学的研究，已明确了这种酶主要与DNA修复有关。因此重新进行与DNA复制有关酶的检索，发现两种新的酶。康伯格最初发现的酶称为
