    • The invention provides a method for reducing stutter in the amplification of a microsatellite comprising the steps of providing a sample comprising a microsatellite having a G+C content of 50% or less; contacting the sample with at least one enzyme having nucleic acid polymerase activity; and incubating the sample with the enzyme for a sufficient amount of time and under conditions sufficient to amplify the microsatellite; wherein the incubation is performed in the presence of an amount of betaine, sorbitol or mixtures thereof, effective to reduce stutter relative to the amount of stutter observed in the absence of betaine and/or sorbitol. The invention also provides compositions containing betaine and/or sorbitol, kits for amplifying microsatellites having a G+C content of 50% or less, and methods of using all of the foregoing.
    • 本发明提供了减少微卫星扩增中的口吃的方法,包括以下步骤:提供包含G + C含量为50%或更少的微卫星的样品; 使样品与至少一种具有核酸聚合酶活性的酶接触; 并将样品与酶温育足够的时间和足以扩增微卫星的条件; 其中在一定量的甜菜碱,山梨糖醇或其混合物的存在下进行培养,其有效地相对于在不存在甜菜碱和/或山梨醇的情况下观察到的口吃量减少口吃。 本发明还提供含有甜菜碱和/或山梨糖醇的组合物,用于扩增G + C含量为50%以下的微卫星的试剂盒,以及使用上述所有方法。

    • Improvements to the in situ polymerase chain reaction (PCR), a process of in vitro enzymatic amplification of specific nucleic acid sequences within the cells where they originate, can be achieved by changing the way that the enzymatic reaction is started. Reaction initiation is delayed until the start of PCR thermal cycling, either by withholding a subset of PCR reagents from the cellular preparation until the preparation has been heated to 50.degree. C. to 80.degree. C., immediately before thermal cycling is begun, or by adding to the PCR reagents a single-stranded DNA binding protein which blocks reaction at temperatures below about 50.degree. C. If the in situ PCR is performed on cellular preparations already attached to a microscope slide, thermal cycling also is facilitated by use of a thermal cycler sample block or compartment designed optimally to hold the microscope slide and any vapor barrier covering the slide.
    • 原位聚合酶链反应(PCR)的改进,其可以通过改变酶反应开始的方式来实现其在其中起源的细胞内的特定核酸序列的体外酶促扩增过程。 反应开始被延迟直到PCR热循环的开始,通过从细胞制剂中扣留一组PCR试剂,直到制备在热循环开始之前立即加热至50℃至80℃,或通过 向PCR试剂中加入在低于约50℃的温度下阻断反应的单链DNA结合蛋白。如果在已经连接到显微镜载玻片上的细胞制剂上进行原位PCR,则通过使用热 循环仪样品块或隔室设计最佳,以保持显微镜载玻片和覆盖幻灯片的任何蒸汽屏障。
