DPPIV is a widely distributed serine protease that cleaves two amino acids from small peptides containing alanine or proline in the second position of the N-terminus of the peptide. DPPIV activity is especially critical for inactivation of GLP-1, a potent antihyperglycemic hormone, inducing glucose-dependent stimulation of insulin secretion. DPPIV inhibitors provide a potent treatment for type 2 diabetes prolonging the activity of GLP-1 and improving insulin secretion and blood glucose control regulation. The SensoLyte® AMC DPPIV Assay Kit provides a convenient method for high throughput screening (HTS) of DPPIV inhibitors and for continuous assay of DPPIV activity using a fluorogenic substrate that has a high reactivity and low background. DPPIV cleaves the substrate resulting in release of AMC (7-amino-4-methylcoumarin) fluorophore. Fluorescence can be monitored at excitation /emission= 354/442 nm. This kit can be used for high throughput screening of DPPIV inhibitors. Kit size: 100 assays. | |

⒈通过嵌入DNA双链的碱基之间,形成稳定复合物,抑制DNA复制与RNA合成,从而阻碍快速生长的癌细胞的分裂。
⒉抑制拓扑异构酶II,影响DNA超螺旋转化成为松弛状态,从而阻碍DNA复制与转录。有研究显示拓扑异构酶II抑制剂(除蒽环类药物还包括依托泊苷等)能够阻止拓扑异构酶II的翻转,而这点对于它从它的核酸底物上脱离是必需的。这就意味着,拓扑异构酶II抑制剂使拓扑异构酶II的复合物在DNA链断裂之后才能更稳定,导致后者催化了DNA的破坏;同时,拓扑异构酶II抑制剂还能阻碍连接酶对DNA的修复。
⒊螯合铁离子后产生自由基从而破坏DNA、蛋白质及细胞膜结构。向左转|向右转
最近遇到了实验上的大问题,就是用一步法做RNA的荧光定量PCR时,发现低浓度的做不出来,而DNA是可以的,想请问各位在一步法PCR中有没有什么高见,就是逆转录的Buffer有没有什么需要注意的地方!就是在逆转录酶的最适Buffer和Taq酶的最适Buffer中寻找一个最适的Buffer!
