GFP、EGFP、YFP、EYFP、CFP的区别 LUYOR

WebYFP（Yellow Fluorescent Protein）是黄色荧光蛋白，其序列与GFP基本相同。 YFP就是把Thr203以Tyr取代，这样的GFP不发出绿色荧光，而发出较长波长的黄色荧光，也就是YFP。因此两者最大的区别则是发射波长了，在其他序列上没有区别。而EGFP是增强型的GFP，发生了双氨基酸取代，Leu (亮氨酸)取代GFP上的Phe64 (苯丙氨酸)，Thr (苏氨 Web@yhHHh jjj 说的属于原子发射谱和原子吸收谱，并不属于荧光光谱的范畴。在光照（激发光）的作用下，荧光分子从基态跃迁到激发态，在从激发态返回到基态的过程中，有可能会发射光子而发光（发射光），如果激发态到基态的跃迁过程是自旋允许的称为荧光，自旋禁阻的称激发光谱与发射光谱有什么区别？详细解释是？知乎
