Overview:
IL-8 or interleukin 8 is a member of the CXC chemokine family that is one of the major mediators of the inflammatory response and several cell types secrete this chemokine. It functions as a chemoattractant, and is also a potent angiogenic factor. IL-8 plays an essential role in the pathogenesis of bronchiolitis, a common respiratory tract disease caused by viral infection (1).IL8 is produced and released from human adipose tissue and from isolated adipocytes in vitro, which may indicate that IL8 from adipose tissue could be involved in some obesity-related complications (2).
Gene Aliases:
NAF; GCP1; LECT; LUCT; NAP1; CXCL8; GCP-1; LYNAP; MDNCF; MONAP; NAP-1

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。
