Overview

product description：

A variety of cyanine 7 dyes has been used to label biological molecules for fluorescence imaging and other fluorescence-based biochemical analysis. They are widely used for labeling peptides, proteins and oligos etc. Cy7 dye conjugates are one type of the most common near infrared red fluorophores used in in vivo imaging applications. Cy7 NHS ester readily reacts with amino groups. We offer Cy dye NHS esters in the form of triethylammonium salts that are more soluble in DMSO and DMF than the corresponding potassium salts that are offered by some other vendors. The Cy dye triethylammonium salts have the same reactivity and give the conjugates identical to the the Cy dye potassium salts.
