The 5-AminoOxy-Modifier 11 contains the tetraethylene glycol linkage for improved solubility and minimizes the effects on hybridization of the oligo. Aminooxy modifiers can be used in chemoselective conjugation reactions with aldehydes and ketones to form stable oximes. The oxime formed from the reaction of these alkyloxyamines creates a stable covalent bond that is compatible with standard oligonucleotide deprotection conditions. Oxime covalent bonds are a more stable than the imine formed by the conjugation of amines with aldehydes, which require subsequent reduction to secondary amines.
Solution Phase Conjugation Solution-phase with direct-conjugation to an aldehyde or ketone provides the best results. Synthesize the oligo DMT-ON and complete the deprotection. After drying, complete the conjugation in 80% acetic acid to simultaneously remove the DMT group and catalyze the oxime formation.
Solid Phase Conjugation The aminooxy conjugation can also be performed on the column after removal of the 5-DMT group, provided the label is stable to the subsequent deprotection conditions. If the oligo will not be conjugated immediately, retain the DMT protecting group and remove with 3% TCA in DCM just prior to the conjugation. - Aminooxy-Modifier-11
