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最一致的电位响应。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。金畔生物是AAT Bioquest的中国代理商,为您提供最优质的膜电位荧光探针Di-4-ANEPPS。
