Modification and Labeling

Glen Research products for modification and labeling are produced and packaged to ensure the highest performance on commercial synthesizers. Every batch is accompanied by an Analytical Report and an HPLC trace, showing the results of our QC testing. Glen Research monomers are packaged in industry standard vials which are specially cleaned to eliminate particulate contamination.

Our backbone modification phosphoramidites and supports are produced and packaged to ensure the highest performance on commercial oliognucleotide synthesizers.

We offer 5'-DBCO-TEG Phosphoramidite for preparing oligos with a 5'-DBCO modification and DBCO-dT-CE Phosphoramidite for inserting a DBCO group at any position within the oligonucleotide. DBCO-sulfo-NHS Ester is also offered for post-synthesis conjugation reactions.

An NHS ester allows the functionalization of an amino moiety in a variety of molecules, including DNA and RNA oligonucleotides, as well as peptides or proteins. NHS esters are especially useful in situations where the equivalent phosphoramidites exhibit instability to the conditions of oligonucleotide synthesis and/or deprotection.
