Fluorescent oligonucleotides are used in a variety of biochemical and analytical applications, such as DNA sequencing, FISH, qPCRand others. We manufacture a lot of different reagents for the synthesis of fluorescent oligonucleotides. Whether you need to make single, multi or dual labeled probes, we have the fluorophores and quenchers you need.
