FAM phosphoramidite, 6-isomer (Pro) is a hydroxyprolinol-derived reagent suitable for 5’ and internal labeling. Hydroxyprolinol-based (FAM) phosphoramidite is a modifying reagent for the synthesis of labeled with fluorescein oligonucleotides.

For the purpose of the introduction of fluorescent labels this type of phosphoramidites is obtained with a 6-aminohexanoate linkage as a spacer between the skeleton and the functional group.

This modifying reagent with the core of hydroxyprolinol, also has a dimethoxythrityl protection group making available reversed phase HPLC (RP-HPLC) or reversed-phase cartridge purification.

Recommendations for using the reagent:

Coupling: 6 min.

Deprotection: Standard conditions with 25 % ammonium hydroxide; deprotection time depends on the composition of nucleic acids and their protective groups.

AMA (1:1 mixture of concentrated aqueous ammonium hydroxide / 40 % aqueous methylamine) can be used for 2 hours at room temperature or 10 min at 65 °C.
