GENEπ数字PCR技术应用教程
数字 PCR( digital PCR ，dPCR ) 下一代DNA/RNA扩增技术。原理是将一个PCR 反应体系分配到大量微小的反应单元中，在每个微反应器中包含或不包含 1 个或多个拷贝的目标核酸分子 (DNA 模板) ，进行“单分子模板”PCR 扩增。扩增结束后，通过阳性反应单元( 通过
基因芯片(gene－chip)的原理
基因芯片(gene chip)的原型是80年代中期提出的。基因芯片的测序原理是杂交测序方法,即通过与一组已知序列的核酸探针杂交进行核酸序列测定的方法,在一块基片表面固定了序列已知的八核苷酸的探针。当溶液中带有荧光标记的核酸序列TATGCAATCTAG,与基因芯片上对应位置的核酸探针产生互补匹配时,通
