Cyanine 7 monosuccinimidyl ester, potassium salt
same as GE Cy7® NHS ester
This Cy7® dye is the same molecule to GE's monoreactive Cy7® NHS ester. It readily reacts with amino groups. Our Cy7® Fluors are thoroughly QC tested to ensure high levels of chromophore and reactive dye content. 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® is the trademark of GE Healthcare.
