This high load, 500 ? controlled pore glass solid support is designed for the synthesis of oligonucleotides containing up to 50 bases with a 3'-amino group. Amino group is protected with trifluoroacetyl (TFA) protection which is easily removed under standard deblock conditions.

The reagent is based on hydroxyprolinol core - a universal non-nucleoside structure that is naturally 100% chiral (no isomers formed upon condensation), and stable to all conditions of oligonucleotide synthesis and deblock.
