Water soluble, amino-reactive sulfo-Cyanine3 NHS ester. Efficiently labels proteins and peptides in purely aqueous solution, without need for organic co-solvent. Ideal for proteins with low solubility, and proteins prone to denaturation.
This is 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.

BDP TMR NHS ester
Amine reactive NHS ester of BDP TMR, bright borondipyrromethene dye for TAMRA channel especially suitable for fluorescence polarization assays.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.sulfo-Cyanine5 DBCO
