产品介绍

膜电位荧光探针Di-4-ANEPPS是美国AAT Bioquest生产的用于膜电位的荧光探针。电位敏感的ANEP染料是两性离子分子，在不同的细胞和组织类型中表现出一致的电位响应。可以通过将原液直接添加到细胞培养基中，使用Pluronic®F-127或通过逆行标记将它们引入细胞。ANEP染料在结合到膜之前是不发荧光的，并且它们对周围环境中的电势变化的荧光响应。ANEP染料是一种快速响应的探针，通过响应周围电场的变化，通过改变其电子结构并因此改变其荧光性质来工作。它们的光学响应足够快，可以检测到兴奋性细胞（包括单个神经元，心脏细胞和完整的大脑）中的瞬态（毫秒）电势变化。然而，它们的电位依赖性荧光变化的幅度通常很小；快速响应探针通常每100 mV显示2-10％的荧光变化。此外，这些染料在其激发光谱中显示出电位依赖性变化，因此可以使用激发比测量定量膜电位。百萤生物是AAT Bioquest的中国代理商，为您提供优质的膜电位荧光探针Di-4-ANEPPS。
