Medchemexpress LLC Sulfo-Cyanine7 NHS ester potassium | 1603861-95-5 | 90.0% | 10 MG
Sulfo-Cyanine7 NHS ester potassium is a water-soluble, amine-reactive N-hydroxysuccinimide (NHS) ester of a near-infrared cyanine dye supplied as the potassium salt. It is used to label primary amines on proteins, peptides, and other biomolecules to produce sulfo-Cyanine7-labeled conjugates for near-IR fluorescence imaging and related research applications.
- Water-soluble near-infrared fluorescent dye.
- Amine-reactive NHS ester for efficient conjugation to proteins.
- Supplied as the potassium salt for enhanced solubility.
- Suitable for labeling proteins, peptides, and other biomolecules.
- Produces stable, near-IR fluorescent conjugates for imaging applications.
