逆转录（reverse transcription）是以RNA为模板合成DNA的过程，即RNA指导下的DNA合成。是RNA病毒的复制形式，需逆转录酶的催化。艾滋病病毒(HIV)就是一种典型的逆转录病毒。
逆转录与反转录严格意义上来说没有什么区别，但是逆转录是RNA类病毒自主行为，在整合到宿主细胞内以RNA为模板形成DNA的过程；反转录是进行基因工程过程中，人为地提取出所需要的目的基因的信使RNA，并以之为模板人工合成DNA的过程。二者虽同为RNA→DNA的过程，但地点不同，相对性的来说，逆转录在体内，反转录在体外。
不过。。。。我时常用那种过期一两年的。。。。也能反转出来。只要你保存得当就可以了。一般是-20以下保存。
