产品介绍
钙离子荧光探针Cal Red R525/650 AM是美国AAT Bioquest生产的钙离子荧光探针,细胞内钙通量测定是一种广泛使用的监测GPCR和钙通道活性的方法。为了量化细胞内钙浓度,比率荧光钙指示剂是优选的,因为该比例与钙浓度直接相关并且与细胞数量和染料加载浓度无关。然而,最流行的比率钙指示剂(例如Fura-2和Indo-1)具有某些限制,例如较低的灵敏度,UV激发,并且与HTS筛选过滤器组不兼容。 Cal Red™R525 / 650已被开发为新的488 nm可激发的比率荧光钙指示剂。 Cal Red™R525 / 650是弱荧光的,一旦进入细胞,亲脂性AM阻断基团被细胞内酯酶切割,导致带负电荷的荧光染料在细胞中保留良好,激发接近488 nm,两次发射在525 nm处, 650纳米。当用生物活性化合物刺激细胞时,该受体启动细胞内钙的释放,其被Cal Red TM R525 / 650螯合。当在488nm激发时,发射信号在525nm处增加并在650nm处减小。 Cal Red™R525 / 650的激发和发射波长与普通滤光片组兼容,对细胞的损伤最小,使其成为评估和筛选GPCR激动剂和拮抗剂以及钙通道靶标的有力工具。金畔生物是AAT Bioquest的中国代理商,为您提供最优质的钙离子荧光探针Cal Red R525/650 AM。
