Product Introduction
Bioactivity
| 名称 | Theophylline |
| 描述 | Theophylline (1,3-Dimethylxanthine) is a methyl xanthine derivative from tea with diuretic, smooth muscle relaxant, bronchial dilation, cardiac and central nervous system stimulant activities. Theophylline inhibits the 3', 5'-CYCLIC NUCLEOTIDE PHOSPHODIESTERASE that degrades CYCLIC AMP thus potentiates the actions of agents that act through ADENYLYL CYCLASES and cyclic AMP. |

XBB.1.5 毒株的传播力为何这么强?北大曹云龙团队最新研究揭示相关机制
,但对于 XBB.1.5 活性较弱。由该团队此前开发的抗体 SA58 同样也被逃逸,不过抗体 SA55 仍然对 XBB.1.5 有效。 图片来源:bioRxiv 与 XBB.1 相比,XBB.1.5 带有额外的 Ser486Pro 突变。先前的深度突变分析结果表明,与 Ser486 相比,Pro486 可能增强了其对 hACE2 的亲和力。 随后,研究人员通过使用表面等离子体共振 (SPR) 技术检测 XBB.1.5 受体结合域 (RBD) 与人 ACE2 (hACE2) 的结合亲和
值最好接近 72℃ GC 含量(composition)过高或过低都不利于引发反应。上下游引物的 GC 含量不能相差太大。另外,上下游引物的 Tm 值(melting temperature)是寡核苷酸的解链温度,即在一定盐浓度条件下,50% 寡核苷酸双链解链的温度。有效启动温度,一般高于 Tm 值 5-10℃。 若按公式 Tm=4(G+C+2(A+T)估计引物的 Tm 值,则有效引物的Tm为 55-80℃,其 Tm 值最好接近 72℃ 以使复性条件最佳。 4、引物 3' 端要避开密码
