Cyanine5.5 NHS Ester is a reactive dye that labels amino groups on peptides, proteins, and oligonucleotides. As an analog of Cy5.5® NHS ester, it emits in the far-red to near-infrared range, making it perfect for low-background fluorescence and in vivo NIR imaging.
Key Features:
- Bright Far-Red/NIR Emission: Stands out in applications needing low background noise, enhancing clarity in imaging and diagnostics.
- Quick and Efficient Labeling: Reacts directly with primary amines in proteins, peptides, and oligonucleotides for reliable conjugation.
- Versatile Replacement: Use it instead of NHS esters of Cy5.5®, Alexa Fluor 680, or DyLight 680.
Cyanine5.5 NHS Ester is your go-to for high-sensitivity detection in fluorescence measurements and imaging, offering bright, stable results with minimal background interference.
AxisPharm offers 5000+ PEG Linkers with high purity. Different kinds of PEG Reagents may be available by custom synthesis.
