荧光入门介绍
荧光是George Gabriel Stokes于1852年首次报道的一种现象。他观察到萤石在紫外线照射后开始发光。荧光是光致发光的一种形式，是指一种材料被光照射后会发射出光子。发射光的波长比激发光更长。这种效应又称为斯托克斯位移。
如何为免疫荧光显微镜制备样本
免疫荧光（IF）是一种用于可视化观察细胞内过程、状态和结构的强大工具。IF制剂可通过多种显微镜技术（如激光共聚焦、宽场荧光、全内反射成像等）来加以分析，具体取决于应用目的或研究人员的关注重点。与此同时，在很多使用至少一套简易荧光显微镜的研究工作组当中，IF早已成为不可缺少的一部分。
荧光染料
荧光显微镜的基本原理是借助荧光染料对细胞成分进行高度特异性的可视化观察。这可能是一种与兴趣蛋白质遗传相关的荧光蛋白，如绿色荧光蛋白（GFP）等。如果克隆无法实现，例如在组织学样本上无法实现，则需要使用另一种技术如免疫荧光染色来对兴趣蛋白质进行可视化观察。为此，人们使用抗体来连接不同的荧光染料并将其直接或间接地结合到适当的靶点上。此外，借助荧光染料，荧光显微镜的应用就不再仅局限于蛋白质观察，还能对核…
探索分离具有重叠光谱的荧光团的创新技术
