PCR - Polymerase Chain ReactionPCR is an in vitro technique for the amplification of a region of DNA which lies between two regions of known sequence. PCR amplification is achieved by using oligonucleotide primers. These are typically short, single stranded oligonucleotides which are complementary to the outer regions of known sequence. The oligonucleotides serve as prim...

Amplification Refractory Mutation System Used to detect point-mutations and small deletions, differentiates between DNA-sequences differing only in 1 nucleotide PCR-primers with 3’ terminus directed against the mutation site to be tested correct 3’ base pairing of a primer is required in order to produce a PCR product Can also be used to detect SNP’s See e...

Real Time PCR A useful new approach? Statistical Problems? Reverse transcription followed by Polymerase Chain Reaction Considered to be the most sensitive method for the detection and quantification of gene expression levels. Used as a follow-up when a particular gene is suggested in micro-array studies. Potential problems with sensitivity, specificity and reproducibil...

PCR产物的电泳检测时间　　一般为48h以内，有些最好于当日电泳检测，大于48h后带型不规则甚致消失。 假阴性，不出现扩增条带　　PCR反应的关键环节有①模板核酸的制备，②引物的质量与特异性，③酶的质量及， ④PCR循环条件。寻找原因亦应针对上述环节进行分析研究。 ……………………

聚合酶链式反应（PCR）过程利用模板变性，引物退火和引物延长的多个循环来扩增DNA序列。这是一个指数增长的过程，因为上一轮的扩增产物又作为下一轮扩增的模板，使其成为检测核酸的一种非常灵敏的技术。一般，经过20-30个循环得到的扩增产物就足够在溴化乙锭染色的凝胶上观察到。反应包括几个成分（表1）。模板可以为纯化的基因组或质粒DNA；由RNA转化得到的cDNA；或未经纯化的粗制生物样品，如细菌克隆或...
