产品介绍

新型钙离子荧光探针Calbryte 520,钾盐是美国AAT Bioquest生产的钙离子荧光探针，钙的测量对于许多生物学研究至关重要。荧光探针显示结合钙的光谱响应，使研究人员能够通过荧光显微镜，流式细胞仪，荧光光谱和荧光酶标仪研究细胞游离钙浓度的变化。随后于1989年推出Fluo-3，后来开发出Fluo-4，Fluo-8和Cal-520，具有改进的信号/信号比。但是，Fluo-4仍存在一些严重问题。例如，对于Fluo-3，在使用Fluo-4的所有细胞内钙测定中，需要使用丙磺舒以防止细胞负载的Fluo-4从细胞中泄漏。探针与基于Fluo-4的钙测定法的使用损害了测定结果，因为丙磺舒被证实具有多种复杂的细胞效应。 Calbryte 520是用于钙测量的新一代荧光指示剂，其大大提高的信噪比和更好的细胞内保留特性使CalBryte 520成为强大的钙指示剂。它具有与Fluo-4相同的激发和发射波长，因此相同的Fluo-4测定设置可以容易地应用于基于Calbryte 520的钙测定。百萤生物是AAT Bioquest的中国代理商，为您提供优质的新型钙离子荧光探针Calbryte 520,钾盐。
