ImmunoChemistry Magic Red 轻松检测细胞内组织蛋白酶B（Cathepsin B）活力

       组织蛋白酶B (Cathepsin B, CTSB)是一种广泛表达于溶酶体上的半胱氨酸肽链内切酶，属于木瓜蛋白酶家族的成员，广泛存在于从病毒到哺乳动物和人等生物体内。可通过参与细胞凋亡、细胞外基质降解、抗原呈递、炎症反应、细胞自噬等多种病理生理过程从而参与多种疾病的发生和发展。   

       市面上常见的是检测细胞裂解液中的组织蛋白酶B活性，更多研究者希望动态检测 活细胞 内的组织蛋白酶B的活性，做更真实的实验！艾美捷科技为您推荐Immunochemistry Tech（ICT）品牌专利Magic Red系列产品。 

       ICT的Magic Red?检测法使研究人员能够在体外对细胞内的蛋白酶活性进行定量和监测。

* 仅供科研使用，不得用于医疗. 

       【原理】Magic Red魔力红底物，是细胞渗透性的，它很容易穿透细胞膜和内部细胞器的膜——不需要裂解或渗透步骤。如果组织蛋白酶是活性的，魔红底物被裂解，甲酰紫荧光团将在激发时变为荧光（Ex/Em =592nm/628nm）。随着酶活性的进展和更多魔红底物的裂解，信号将增强，使研究人员能够观察颜色随时间的变化。样品可通过荧光显微镜或荧光酶标仪进行分析。试剂盒中包括Hoechst 33342和吖啶橙，分别用于检测核形态和溶酶体细胞器结构。
