Bio-Synthesis offers C3 Spacer oligonucleotide modification at various scales. The C3 propyl spacer can be incorporated internally or at the either end of the oligo during chemical synthesis. Multiple C3 spacers can be added to introduce a longer spacer arm for the attachment of fluorophores or other pendent groups.
Spacer C3-modified oligos have been used in a number of different applications, including protein-RNA functional studies1 , as a DNA abasic site mimic to study the utility of small synthetic ligands (such as pteridines) for nucleotide recognition in SNP typing applications2, and for solid-phase immobilization of hybridization probes3 . Spacer C3 incorporated at the 3’-end of an oligo functions as an effective blocking agent against polymerase extension at that end in PCR reactions4
