Glen Research 2'-F-G-CE Phosphoramidite, 0.5 g, Guanosine, 2'-Fluoro, CE (β-cyanoethyl)

This product is a 2'-Fluoro Guanosine CE Phosphoramidite, supplied by Glen Research, designed for oligonucleotide synthesis. It features a 2'-fluoro modification that enhances the thermal stability of duplexes with RNA by approximately 2°C per residue. This phosphoramidite is optimized for efficient synthesis and contributes to the development of chimeric oligonucleotides that bind tightly to RNA targets and resist nuclease degradation, particularly with phosphorothioate linkages.
