Cambridge 112774 CAMBRIDGE ATTO 647 Fluorescent Label

Product Description

The Cambridge ATTO 647 with MPN 112774 is a fluorescent label designed for applications in the red spectral region. This label shows strong absorption properties and has a high fluorescence quantum yield. The dye is zwitterionic, which means it carries no net electrical charge and remains stable in a range of physiological pH values and buffers up to pH eight. The ATTO 647 is also hydrophilic, optimizing fluorescence excitation between six hundred fifteen and six hundred sixty nanometers.

• Strong absorption and high fluorescence quantum yield
• High photo-stability and good water solubility
• Zwitterionic dye stable at physiological pH levels

Product Highlights

This product is ideal for researchers needing reliable fluorescent labels for biological applications.
