Helix Fluor™ 545, succinimidyl ester
FAM, TET, VIC, JOE, NED, TAMRA and ROX fluorescent dyes are frequently used for labeling oliogs. These fluorescent oligo conjugates are often used for nucleic acid sequencing and nucleic acid amplification. Our Helix Fluor™ 545 is an excellent alternative to the VIC dye for preparing fluorescent oligos as they have almost identical spectral properties. Compared to VIC, Helix Fluor™ 545 is much more water-soluble.
![Fluorescent dye NHS esters (or succinimidyl esters) are the most popular tool for conjugating dyes to a peptide, protein, antibody, amino-modified oligonucleotide or nucleic acid. NHS esters react readily with the primary amines (R-NH<sub>2</sub>) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. The resulting dye conjugates are quite stable.](/_next/image?url=https%3A%2F%2Fimages.aatbio.com%2Fproducts%2Ffigures-and-data%2Fhelix-fluor-545-succinimidyl-ester%2Ffigure-for-helix-fluor-545-succinimidyl-ester_wNtyf.jpg&w=640&q=75)
