Cyanine5 maleimide is a mono-reactive dye which selectively couples with thiol groups (for example, with cysteines in peptides and proteins) to give labeled conjugates.
Cyanine5 is an analog of Cy5®, a common fluorophore which is compatible with various instrumentation like microscopes, imagers, and fluorescence readers.
For the labeling of antibodies and sensitive proteins we recommend to use the water soluble sulfo-Cyanine5 maleimide.
Cy5 马来酰亚胺是一种单反应性染料，可选择性地与硫醇基团（例如，与肽和蛋白质中的半胱氨酸）偶联，形成标记的偶联物。
Cyanine5 是 Cy5® 的类似物，Cy5® 是一种常见的荧光团，与显微镜、成像仪和荧光阅读器等各种仪器兼容。
对于抗体和敏感蛋白的标记，我们建议使用水溶性磺基-Cyanine5 马来酰亚胺。
