Bio-Synthesis offers a wide variety of backbone modified oligonucleotide synthesis to increase oligonucleotide affinity to its complementary strands which often results in drastic improvement in specificity and sensitivity for applications where detection of small or highly similar DNA or RNA targets. These backbone and linkage modified oligonucleotides not only possess strong affinity-enhancing effects but also increase resistance to endo and exonucleases which leads to high in vitro and in vivo stability.

We offer the following modifications:
