DegeneratePCR,ashortguide.
What is degenerate PCR? Degenerate PCR is in most respect identical to ordinary PCR, but with one major difference. Instead of using specific PCR primers with a given sequence, you use mixed PCR primers. That is, if you do not know exactly the sequence of the gene you are going to amplify, you insert "wobbles" in the PCR primers where there is more than one possibility. For instance if you ......阅读全文

递减聚合酶链式反应的简介
递减PCR,亦称降落PCR(touchdown PCR)是一种PCR(聚合酶链式反应)方法,用来避免非特异性序列的扩增。PCR中引物的黏合温度(annealing temperature)决定了黏合的特异性,温度越高特异性越强,但过高则不能实现引物和模板的结合,而过低会产生大量非特异性产物。因此

TAILPCR(thermal-asymmetric-interlaced-PCR)简介
在分子生物学研究中,基因克隆和分子杂交的探针制备等操作常需分离与已知DNA序列邻近的未知序列,TAIL-PCR又叫热不对称交错PCR,能够较好地解决上述难题。该技术通过3个嵌套的特异性引物分别和简并引物组合进行连续的PCR循环,利用不同的退火温度选择性地扩增目标片段,所获得的片段可以直接用做探针标记
常规杂交反应存在的问题
常规杂交反应由于受到探针解链温度、溶液中靶序列的初始浓度及探针长度的影响。样品中不同探针所对应的靶序列的拷贝数不尽相同,探针的解链温度也难以保持一致,这样不同位点的杂交速度并不完全与各自靶序列的拷贝数成正比,检测结果也就不具有良好的平行性。所以必需选择最理想的条件以尽可能使正确配对的序列不被遗漏

普通PCR梯度PCR-原位PCR-荧光定量PCR仪的区别
