Lipopolysaccharides (LPS) are characteristic components of the cell wall of Gram negative bacteria; they are not found in Gram positive bacteria. They are localized in the outer layer of the membrane and are, in noncapsulated strains, exposed on the cell

PCR/qPCR/dPCR实验设计

整个PCR工作流程易受引入变量的影响。许多变量无法避免，例如样本来源和逆转录步骤的要求。实验设计也波动较大，可能决定PCR的成败，影响实验的可重复性和灵敏度。

铂催化剂

我们提供高效的铂催化剂，例如二氧化铂（也称为Adams催化剂），适于在有机合成中氢化和脱氢各种官能团。其在反应过程中会形成活性Pt催化剂铂黑。利用铂催化能够在炔烃上诱导顺式加成，形成顺式烯烃。使用铂催化剂的两个最重要的转化包括将硝基化合物氢化为胺、以及将酮氢化为醇。值得注意的是，烯烃的还原可以在硝基存在下用Pt催化剂Adams催化剂进行，而硝基不会被还原。将硝基化合物还原成胺时，铂催化剂表现优于钯催化剂，可最大限度避免氢解作用。该Pt催化剂还用于磷酸苯酯氢解——钯催化剂无此能力。
