Glen Research offers a range of different 5’-Amino-Modifiers designed for use in automated synthesizers to functionalize the 5’-terminus of a target oligonucleotide with a primary amine. These modifiers vary based on the amine protecting group and the linker. Of these, the trifluoroacetyl (TFA)-protected Amino-Modifiers are typically used when a trityl group is not necessary. The TFA group allows deprotection to be completed in a single standard step to give an amine that is immediately available for conjugation with amine-reactive agents.
The 5’-Amino-Modifier C3-TFA has a 3-carbon linker with a TFA protecting group.
It should be noted that TFA-amino modifiers are sensitive to prolonged transit times and elevated temperatures (e.g., international shipments in the summer). Under these conditions, PDA-amino modifiers are significantly more stable and are excellent alternatives (https://www.glenresearch.com/reports/gr25-16).
