各种染料对应的激发波长和吸收波长

常用荧光染料的激发和发射波长备注：发射波长的颜色及频率荧光染料的使用吖啶橙：吖啶橙是最经典的灵敏的荧光染料，它可对细胞中的DNA和RNA同时染色而显示不同颜色的荧光，DNA呈绿色荧光，RNA呈橙红色荧光。

EB:染色DNA和RNA 荧光素双醋酸酯(FDA)：FAD本身无荧光,无极性,可透过完整的原生质膜。

一旦进入原生质体后,由于受到酯酶分解而产生具有荧光的极性物质荧光素。

它不能自由出入原生质膜，因此有活力的细胞能产生荧光,无活力的原生质体不能分解FAD无荧光产生。

5mgFDA溶于1ml丙酮中,避光4℃下贮存,使用时取贮存液加入L甘露醇中.使用时,使最终浓度为%。

荧光染料Ho33342和若丹明123:活细胞双荧光染色观察细胞核和线粒体。

一般的生物染料不能穿透细胞膜，只有当细胞被固定后改变了细胞膜的通透性，染料才能进入细胞内。

但有些活体染料能进入活细胞，并对细胞不产生毒性作用。

荧光染料Ho33342和若丹明123都是活体染料。

Ho33342能与细胞中DNA进行特异的结合，若丹明123能与线粒体进行特异的结合。

采用两种荧光染料的混合染液可对一个活细胞的核和线粒体同时染色。

荧光组化实验中应注意的几个问题：1．每种荧光染料，均有自己的最适PH值，此时荧光最强。

当pH改变时，不仅荧光强度减弱，而且波长将有所改变，因此荧光检测时要在一定的PH值的缓冲液中进行。

2．一放荧光染色在20℃以下时荧光比较稳定，温度升高常出现温度猝灭。

3．在荧光观察中，常因激发光的增强而使样品荧光很快衰竭，造成观察和照相困难。

为此最好用能量小的长波长光进行观察，需照相时再适当增强激发光。

4．一般荧光染液的浓度在万分之一以下，甚至亿万分之一，也能使标本着色。

在一定的限度内，荧光强度可随荧光素的浓度增加而增强，但超过限度，荧光强度反而下降，这是由于荧光分子间的缔合而使自身荧光猝灭所致。

DAPIDAPI即4',6-二脒基-2-苯基吲哚(4',6-diamidino-2-phenylindole)，是一种能够与DNA强力结合的荧光染料，常用于荧光显微镜观测。

因为DAPI可以透过完整的细胞膜，它可以用于活细胞和固定细胞的染色。

DAPI介绍在荧光显微镜观察下，DAPI染剂是利用紫外光波长的光线激发。

当DAPI与双股DNA 结合时，最大吸收波长为358nm，最大发射波长为461nm，其发散光的波长范围含盖了蓝色至青绿色。

DAPI也可以和RNA结合，但产生的荧光强度不及与DNA结合的结果，其发散光的波长范围约在500nm左右。

DAPI的发散光为蓝色，且DAPI和绿色荧光蛋白(Green fluorescent protein, GFP)或Texas Red染剂(红色荧光染剂)的发散波长，仅有少部分重叠，研究员可以善用这项特性在单一的样品上进行多重荧光染色。

DAPI能快速进入活细胞中与DNA结合，因此DAPI对生物体而言，也被视为一种毒性物质与致癌物。

使用过程中应注意操作与抛弃的处理程序。

中文名：4，6-联脒-2-苯基吲哚(?)英文名：4',6-diamidino-2-phenylindole，2-(4-amidinophenyl)-1H -indole-6-carboxamidine，DAPI dihydrochloride分子式：C16H15N5分子量：277.324CAS number：28718-90-3光谱性质：DAPI的最大激发波长为340nm，最大发射波长为488nm与双链DNA结合时最大吸收/最大发射为358 nm/461 nm；与RNA结合时，最大发射移动到400 nm左右。

DAPI染色原理：DAPI 为一种荧光染料，可以穿透细胞膜与细胞核中的双链DNA结合而发挥标记的作用，可以产生比DAPI自身强20多倍的荧光，和EB相比，对双链DNA的染色灵敏度要高很多倍。

各样激发光和汲取光波长此刻发现一个更全的相关激发光和发射光的波长图谱。

这对 CONFOCAL去做多重染色时是必不行少的参照资料。
