Spacer 9, spacer 18, Spacer C12, Spacer C3 can be inserted in multiple location within can oligonucleotide when a longer spacer is required. Spacer 9 is a triethylene glycol chain that is 9 atoms long (6 carbons + 3 oxygens). Spacer 9 has been used in various applications example such as using spacer 9 to form non-nucleotide bridges in hairpin loops in oligonucleotides Spacer 9 modified oligonucleotides can be used for epitope drug developmen. Other application such as solid-phase immobilization of hybridization probes. Multiple addition of Spacer 9 has been used to form long, flexible linker arms between the two domains of a bifunctional DNA oligonucleotide, in order to maximize the binding flexibility.
