Helix Fluor™ 575, succinimidyl ester

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.

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™ 575 is an excellent alternative to the NED dye for preparing fluorescent oligos.
