Bio-Synthesis offers left-handed helical L-RNA oligonucleotide synthesis at various scales. The L-RNA base can be incorporated internally or at the either end of the oligonucleotide as well as chimeric L-DNA, D-DNA , D-RNA design. These artificial oligoncueltoide are enantiomeric of natural RNA. L-RNA are Spiegelmers , mirror image of D-ribose. Like aptamers, they are able to bind target moelcule such as peptides, proteins , or low molecular weight substance at nanomolar range. They have high resistant to nuclease degradation and exhibit low antigenicity. RNA Spiegelmers offers an alternative approach for RNA based drug discovery.
