Biological Activity
Vitamin D receptor (VDR) agonist; analog of calcitriol (Cat. No. 2551). Exhibits anti-tumor and anti-proliferative activity with reduced hypercalcemic effects. 60 times more potent in inhibiting MCF-7 cell growth in vitro; also shown to induce autophagy in MCF-7 cells. Reverses the effects of parathyroid hormone-relatedprotein (PTHrP).Technical Data

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。
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。
