RNase-Free Grade
In molecular biology and cell biology research, RNA is the biomacromolecule most prone to degradation. RNases widely present in the environment and samples have strong activity; even extremely low levels of contamination can rapidly destroy RNA during extraction, quantification, reverse ...
无RNA酶级
在分子生物学与细胞学研究中，RNA是最容易被降解的生物大分子。环境与样本中普遍存在的RNA酶（RNase）活性很强，即使极低水平的污染，也会在提取、定量、反转录或建库等步骤中快速破坏RNA，导致重复性差、Ct漂移、文库失败等问题。 ...
选择“用于荧光分析”的试剂：一份实用指南
“用于荧光分析”（亦常写作“用于荧光光谱”）指的是一类试剂——最常见为溶剂——其在生产与质量控制（QC）环节被明确限定为极低自发荧光与极低紫外吸收，从而不增加背景、也不扭曲激发/发射光谱。实践中，该标识可视作“用于光谱/分光光度”等级中的一个子集：除强调 UV/Vis 透明度外，还对背景荧光进行明确控制。供应商通常通过 UV–Vis 吸收扫描（多在1cm光程条件下给出 Aλ ...
Choosing Reagents ‘for Fluorescence Analysis’: A Practical Guide
“For fluorescence analysis” (often written “for fluorescence spectroscopy”) designates reagents—most commonly solvents—manufactured and QC-tested to have very low self-fluorescence and very low UV absorbance so they don’t add background or distort emission/excitation spectra. In practice, this ...
