钙离子荧光探针 Fura-2
Fura-2是一种广泛使用荧光钙离子探针。Fura-2结合钙离子后，荧光的***大激发波长从363nm（未结合钙离子时）迁移到335nm（钙离子饱和时），同时荧光的发射***大波长在510nm左右，相对未变。一般用340nm和380nm波长激发Fura-2，通过使用与两种激发对应的荧光强度比率来计算细胞内的钙离子浓度。钙离子浓度测量使用比率法避免了不均匀染色和光致漂白的干扰。Fura-2已在很多细胞系统和应用中使用，尤其是在显微成像技术里。
Furaptra，通常也被叫做Mag-Fura-2，***初是由荧光镁离子探针发展而来的。通常钙离子浓度范围在1µM 到 100 µM时Fureptra是非常出色的钙离子探针。Fura-2 和Furaptra带有同样的生色基团，在钙离子浓度变化时有着相似的光谱变化。
