一般說明

Abberior STAR 488是STED显微镜的最新发展。它是一种非常明亮的绿色荧光染料,可以在主要的488 nm激光波长上非常有效地被激发。Abberior STAR 488可以替代Oregon绿488、Atto 488或Alexa Fluor 488等染料。
STED:在STED显微镜中可在585-605 nm处最有效地耗尽染料。

Abberior STAR 488是可在488 nm处激发的染料。并且,该染料专门设计和测试与我们的STAR 440Sx(在590 nm处激发)进行联合使用,用于双色STED显微镜中。该染料已在Leica 双色TCS STED CW显微镜中成功测试。

关键特性
  • 可在488 nm激发的STED染料
  • 在STED显微镜中的理想耗尽行为(〜590 nm)
  • STAR 440SX的双色标记组合,可用于双色STED显微镜

荧光寿命,τ: 3.9 ns (MeOH)

應用

抗兔IgG抗体® STAR 488抗体已作为二抗用于:
  • 在前列腺癌细胞系PPC-1和TSU-Pr1中进行荧光免疫组化分析
  • 用于HeLa和猴肾COS-7细胞的免疫荧光中
  • OLN-t40-α-syn细胞(少突胶质细胞)中的STED(刺激发射损耗)显微镜分析

適合性

Stimulation emission depletion (STED) microscopy breaks the spatial resolution limit of conventional light microscopy while retaining its major advantages, such as working under physiological conditions. These properties make STED microscopy a perfect tool for investigating dynamic sub-cellular processes in living
