SafeStain® GelStain® Nucleic Acid Gel Stain(>SafeRed)
SafeStain® Nucleic Acid Gel Stain is our 4th generation of fluorescent nucleic acid gel stain designed to replace GelRed, GelGreen, Sybr Safe, Sybr Gold and the highly toxic ethidium bromide (EtBr). The Ames test confirmed that are nonmutagenic at concentrations well above their working concentrations used for gel staining. Nucleic Acid Gel Stain is highly sensitive than EtBr either as precast gel stains or post gel stains. SafeStain is suitable for all the existing electrophoresis imaging system including standard transilluminator(280～380nm) and Blue light instrument (similar visible light 450～500nm) without changing your existing imaging system. SafeStain® can also be used to stain dsDNA, ssDNA or RNA in polyacrylamide gel via post gel staining. Precast polyacrylamide gel staining with SafeStain® is not recommended because of relatively high background fluorescence. Furthermore, Polyacrylamide gel staining with SafeStain can be watched by the eyes.
SuperFluor 488 Phalloidin标记鬼笔环肽 Actin-Tracker Green-488 (微丝绿色荧光探针)
鬼笔环肽（Phalloidin）是一种来源于毒蕈类鬼笔鹅膏（Amanita phalloides）的环状七肽毒素，以高亲和力（Kd= 20 nM） 选择性结合于丝状肌动蛋白 F-actin，而不会与单体肌动蛋白 G-actin 结合。鬼笔环肽衍生物也以相近的亲和力结合于大小纤维，无论是动植物来源的肌肉细胞或非肌肉细胞，按照每一个肌动蛋白亚基约与一个鬼笔环肽分子的计量比结合， 且非特异性结合几乎可忽略，染色区域和非染色区域辨识度非常明显，因此，鬼笔环肽衍生物特别适合替代肌动蛋白（Actin）抗体进行相关研究。另外，鬼笔环肽（Phalloidin）的结合可以阻止丝状肌动蛋白（微丝）的解离，稳定微丝结构，从而破坏微丝的聚合-去聚合的动态平衡。此特性使得肌动蛋白聚合发生的临界浓度（CC）降至＜1 µg/mL，因此，可用作一种聚合促进剂。此外，鬼笔环肽还可抑制 F-actin 的 ATP 水解活性。
PKH67 绿色细胞膜染色试剂盒 PKH67 Green Fluorescent Cell Linker Mini Kit
荧光染料PKH67 适⽤于常规细胞膜标记，是⼀种可对体外和体内细胞示踪的绿⾊荧光染料，通过与膜结构的脂质分⼦结合⽽标记细胞。
主要⽤于细胞体外标记、体外细胞增殖研究以及体内外的细胞示踪研究。PKH67的体内荧光半衰期为10-12天。相⽐于PKH-67，PKH-26具有更⻓的半衰期，标记在兔红细胞上的PKH26半衰期⻓达100天以上。特别适⽤于体外增殖研究以及⻓期的体内细胞跟踪研究。PKH67标记细胞后通常⽤流式细胞仪进⾏细胞增殖检测。
