Water soluble, amino-reactive sulfo-Cyanine3 NHS ester that efficiently labels proteins and peptides in purely aqueous solution without needing organic co-solvent. Ideal for proteins with low solubility and proteins prone to denaturation.
This is the sulfonated, hydrophilic, and water-soluble dye. Non-sulfonated Cyanine3 NHS ester is also available.
This product is an analog of Cy3® NHS ester. sulfo-Cyanine3 NHS ester replaces Cy3® and DyLight 549 for all applications.

1-Ethynyl pyrene
Pyrene is a polyaromatic hydrocarbon containing four fused rings. This reagent contains a terminal alkyne group for click chemistry and other reactions, such as Sonogashira coupling.sulfo-Cyanine7 maleimide
Water-soluble near-infrared dye maleimide for the labeling of proteins and peptides.THPTA ligand
THPTA is a water-soluble ligand for Cu(I)-catalyzed click chemistry. The ligand stabilizes copper in its Cu(I) oxidation state. Due to high aqueous solubility, reactions with this ligand do not require an organic co-solvent.General properties
