BioPharm Laboratories" liquid thrombin is a high purity bovine thrombin stabilized in 50% glycerin. Due to thombin"s high proteolytic specificity, thombin is an important protein in recombinant fusion protein purification processes. It is used to cleave His Tags and GST Tags with a high degree of specificity. We express our units in US Units (aka, NIH Units) measured by coagulation. There are approximately 5 Thrombin cleavage units for every one US Unit.

我在做5RACE,选用TaKaRa公司的RNA反转录酶(RNaseH-),不知道这个酶好不好,有什么需要注意的。
多谢……
没有序列识别的功能,他就是简单的催化相邻DNA链的5-P末端和3'-OH末端以磷酸二酯键结合的反应,需ATP作辅酶。 不仅可以催化粘性末端之间或平滑末端之间的DNA的连接,也催化DNA与RNA之间以及少数RNA之间的连接。
反转录酶(Reversetranscripatase)是以RNA为模板指导三磷酸脱氧核苷酸合成互补DNA(cDNA)的酶。哺乳类C型病毒的反转录酶和鼠类B型病毒的反转录酶都是一条多肽链。鸟类RNA病毒的反转录酶则由两上亚基结构。真核生物中也都分离出具有不同结构的反转录酶。
