Cyanine 7 amine [equivalent to Cy7® amine]

A variety of cyanine 7 (Cy7®) 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® amine reacts with carbonyl groups. Cy7® is the trademark of GE Healthcare.
