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成为最强大的钙指示剂。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。金畔生物是AAT Bioquest的中国代理商,为您提供最优质的新型钙离子荧光探针Calbryte 520,钾盐。
