FAM Phosphoramidite, 6-isomer (hydroxyprolinol) serves as a versatile reagent for 5’ and internal labeling of oligonucleotides. It facilitates the synthesis of fluorescein-labeled strands. The 6-aminohexanoate linkage acts as a spacer between the nucleotide skeleton and the functional group. Additionally, this reagent features a dimethoxythrityl protection group, enabling purification via reversed-phase HPLC or cartridge methods.
