6-methoxy Naphthalene Acetic Acid is a competitive and non-selective COX inhibitor with Ki values of 21 and 19 μM for ovine COX-1 and -2, respectively [1][2][3].
Cyclooxygenase (COX), also known as prostaglandin-endoperoxide synthase (PTGS, PGHS), is an enzyme responsible for formation of prostanoids, including thromboxane and prostaglandins such as prostacyclin. COX-1 is the constitutive isoform and is mainly responsible for the synthesis of cytoprotective prostaglandins in the gastrointestinal tract (GI) and of the proaggregatory thromboxane in blood platelets. COX-2 is inducible and short-lived that is stimulated by endotoxin, cytokines, and mitogens. COX-2 plays important roles in prostaglandin biosynthesis in inflammatory cells the central nervous system [1][2].
6-methoxy Naphthalene Acetic Acid (6-MNA) is a competitive and non-selective COX inhibitor with Ki values of 21 and 19 μM for ovine COX-1 and -2, respectively [1][2]. 6-MNA is a metabolite of nebumetome. 6-MNA inhibited human recombinant COX-1 and -2 with IC50 values of 70 and 20 μM, respectively [1].

配后是否应该分装,因为不能反复冻融?
多谢!

我做的双酶切反应,酶分别是宝生物的BamHI和XhoI,双酶切体系是:载体及目的片段分别是30ul,通用buffer4ul,XhoI、BamHI各2ul,无核酶水2ul,总体积40ul。载体和目的片段都是经37度酶切6h。载体上面这两个酶切位点的距离是6个碱基,目的片段是由pcr反应获得的,从puc19中p出来的,两端带有这两种酶的酶切位点,酶切完成后,做连接反应,体系如下:目的片段(全长1441bp)4ul,无核酶水3ul,10*T4DNA连接酶缓冲液1ul,载体1ul,T4DNA连接酶1ul,总体积10ul。16度过夜。之后摇菌送沉菌测序结果回来,送了5管一个都不对。重复实验两次还是不对!
之后改为先用BanHI单切载体,体系如下:载体17ul,酶1ul,buffer2ul,总体积20ul,30度切6小时后,Promega纯化试剂盒直接纯化,完了之后再用XhoI,37度酶切6小时,体系如上,再次用promega纯化试剂盒纯化,目的片段用双酶切体系酶切,之后做连接反应,之后铺板,挑取菌落共10个,摇菌13小时,取菌液做pcr鉴定,结果10个菌落全是引物2聚体,跑出来的条带都是100bp左右。
各位老师这是怎么回事呢?为什么连接不上呢?小弟先谢过各位大哥了!
求问酶切体系为10ul,内切酶1ul,37℃水浴45min,不知道DNA产物是否完全被切开了?
所用内切酶信息如下
同一管dna有的酶可以切开,比如dra1,ecoR1,Hind111
有的酶又完全不能切动,如BamH1,sac1,xba1,xho1,pst1
请问高手这是什么原因??
感谢赐教~!
