Bio-Synthesis offers Biotin-TEG oligonucleotide modification services. Biotin-TEG has an extended 15 atom triethylene glycol spacer arm, and it can be incorporated at either the 5', 3' or internally. The spacer acts to minimize steric hindrance between the biotin moiety and the oligo, thereby can be beneficial for attaching oligonucleotide to nanospheres or magnetic beads.
