简介：帮助的酸水解作用被建立准备-carra-oligosaccharides的微波的一个快速的方法。最佳的水解作用条件被直角的测试决定。oligosaccharides的聚合(DP)的度被高效检测薄层层析(HPTLC)和polyacrylamide胶化电气泳动(页)。就HPTLC和页的结果而言，微波的最佳条件帮助了酸水解作用被决定。-carrageenan的集中是5mgmL<啜class=“a-plus-plus”>1；反应答案被适应pH3与冲淡盐酸酸；答案为在这些indic燬?燬的15个变化是在在100点的微波照耀下面的hydrolyzed吗？？

简介：这份报告描述了能够基于调停toehold的海滨排水量反应(toehold-SDR)和microbead俘获技术的联合在正常温度检测单个核苷酸多型性的一个免费酶、方便、便宜的genotyping生物传感器。生物传感器由一根记者探针和一根俘获探针形成的pre-hybridized海滨组成。面对一个变异的序列，没有调停toehold的海滨排水量，记者探查不能被免除pre-hybridized海滨。Microbeads俘获荧光灯通过biotin-streptavidin相互作用的pre-hybridized海滨microbeads给出重要荧光信号，当在答案没有荧光时。面对一个匹配的目标，然而，海滨排水量有效地被开始，记者探查被免除pre-hybridized海滨。在增加microbeads以后，解决方案生产明亮的荧光，当时microbeads没有明显的信号。遗传型根据答案的荧光紧张方便地被识别。方法提供简单、便宜的策略检测点变化。而且，这个生物传感器在1-40 的范围显示出线性关系；nmol/L和活动范围0.3 的察觉限制；nmol/L。
