CGHofPCRAmplifiedMicrodissectedDNA
PCR:We generally use 1-2 ul of starting paraffin microdissected DNA for each 50 ul DOP-PCR reaction.We assume that about 1 ug of product is produced in each DOP-PCR reaction. The entire product is then nick translated as described below.Nick Translation of the PCR Product:For the first CGH, our approach is to start with predefined test and reference labels, and then to do a replicate ("inverse") reaction ba......阅读全文

巢式PCR(Nested－PCR)定义、原理和步骤
巢式PCR的定义巢式PCR是一种变异的聚合酶链反应(PCR)，使用两对（而非一对）PCR引物扩增完整的片段。第一对PCR引物扩增片段和普通 PCR相似。第二对引物称为巢式引物（因为他们在第一次PCR扩增片段的内部）结合在第一次PCR产物内部，使得第二次PCR扩增片断短于第一次扩增。巢 式PCR的好处
