溶酶体染色试剂盒(蓝/绿/橙/红色荧光)— 超越LysoTracker!
溶酶体(Lysosomes)是动物细胞中重要的细胞器, 其存在的完整性与动物生理病理均密切相关。溶酶体是真核细胞中为单层膜所包围的细胞质结构,内部pH 4~5,含丰富的水解酶,具有细胞内的消化功能。新形成的初级溶酶体经过与多种其他结构反复融合,形成具有多种形态的有膜小泡,并对包裹在其中的分子进行消化。因此,溶酶体具有溶解或消化的功能,为细胞内的消化器官。
目前客户所用的溶酶体荧光染料一般为Invitrogen公司的LysoTracker产品,但是由于其细胞毒性,LysoTracker在染色几个小时后便失去检测效应,更不能随细胞传代而持续示踪染色。另外,LysoTracker的较容易淬灭的光学不稳定性也经常被一些研究者所诟病。
广大研究者急需一款可以长效的溶酶体染料(溶酶体染色试剂盒),便于观察。
向您推荐全新一代的溶酶体染色试剂盒系列产品:LysoBrite™ 溶酶体染色试剂盒,它被设计用来标记活细胞的溶酶体,使之带上不同颜色的荧光。本试剂盒使用一种专属染料,选择性地在溶酶体中积累,是一种疏水性复合物,可以轻易地渗透进入活细胞中,且当进入细胞后就被锁定在溶酶体中,长期保留。
