Long Tether Biotinylated Oligonucleotides
We can now synthesize long and super-long biotinylated oligonucleotides to satisfy your desired tether length to the biotin moiety. It is possible for us to offer biotin tethered through linkers of 56, 73, 90, and 107 atoms in length. You can choose from biotin on the 5′-end or internally on the oligo. A sampling is shown below..
