The high purity bovine thrombin (> 2200 U/mg protein) is used by many diagnostic companies worldwide to defibrinate plasma, producing serum matrixes to be used as controls and standards or in polyclonal antibody production. Using bovine thrombin in polyclonal antibody production to defibrinate plasma may increase antibody yields by 15-20% over off-the-clot methods of defibrination. (BioPharm Defibrination Protocol)Our high purity thrombin is also 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.

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。
TERT是端粒酶逆转录酶
人的端粒酶是由端粒酶逆转录酶、端粒酶RNA和一种假尿嘧啶合成酶组成
