构建cDNA文库的层析柱cDNA分级
这一步稍不注意会影响成功性或影响获得的cDNA的片段分布特点。这一步的操作要小心，尤其要在加入cDNA之前通过反复悬浮和试滴保证柱子能正常工作，cDNA的加入和收集要精力集中。获得的每一级的cDNA量很少，检测时带型很暗，所以要用新鲜做的透明薄胶检测，根据检测结果一定要舍弃太短的cDNA（一般4

如何获得cDNA
cDNA的获取方法：1.用亲和层析法得到 mRNA 后，根据 mRNA 分子的 3' 端有 poly (A) 尾结构的原理，用 12~20 个核苷酸长的 oligo 与纯化的 mRNA 混合， oligo （ dT ）会与 poly (A) 结合作为反转录酶的引物，随机引物法合成的产物也是
cDNA文库构建
cDNA文库[原理]：cDNA文库不同于基因组文库，被克隆DNA是从mRNA反转录来源的DNA。CDNA组成特点是其中不含有内含子和其他调控序列。从而做cDNA克隆时应是先从获得mRNA开始，在此基础上，通过反转录酶作用产生一条与mRNA相互补的DNA链，然后除掉mRNA，以第一条DNA链为模板复制

如何检测cDNA
一般都可以用电泳检测是否合成适当大小片段的带，如果你是想看它的大小肯定可以，如果想看他碱基有没有出错当然还是测序或者使用探针检测，就是比较麻烦
