加尾法是采用加A酶先对mirna进行加尾,然后再用带oligodt的引物反转录,他的反转录引物是通用的,一次反转录可以获得所有miRNA的cdna,效率高。茎环法是采用特异性反转录引物序列+颈环结构作为反转录引物进行反转录的,一次反转录只能获得一种mirna的cdna,可能有几种一起反转录的,这个我不太清楚一起反转录的效果。然后茎环法的经典即ABI的探针法定量试剂盒。我用过茎环法反转录+染料法定量的,下游引物为通用引物,结果不太好,就现在用的这家的他采用的是双向引物都是特异性的,效果还可以。不知道我说的清楚不,希望能对你有帮助。

大家又没有用过,这个公司的酶据说很好啊。
TAKARA的RR047A逆转录试剂盒,做逆转录程序设置错误本来应该37℃15min85℃5s,变成37℃15s,85℃
5s,请问再重新设置程序可以吗,85℃酶会全部失活吗?
