RNA Oligo Synthesis

Bio-Synthesis supplies Custom RNA Oligo Synthesis services for a wide range of labels, modifications, scales and purities. We provide RNA synthesis for long RNA oligos up to 300 bases.

RNA oligos are synthesized using the latest nucleic acid technology and are purified using RNase free PAGE electrophoresis combined with HPLC. Our RNA oligonucleotide synthesis services are provided with mass spectrometric analysis. Purified RNA oligonucleotides come with stringent analytical HPLC or gel electrophoresis to determine final purity.

RNA oligonucleotides are processed using our RNaseSAFETM service, in which RNA oligos are packaged in RNase free matrix tubes to prevent degradation during shipping and storage. This standard service helps safeguard the biological activity of RNA oligos.

For additional information on RNA synthesis services such as RNAi, siRNA, shRNA, mRNA, please contact us or send an email to info@biosyn.com.

RNA synthesis and deprotection is performed using proprietary parallel synthesis and deprotection technologies. This advanced technology enables us to synthesize oligos with higher coupling efficiency and fast deprotection, resulting in quick turnaround time.

Custom Long RNA Oligo Synthesis

Bio-Synthesis is able to chemically synthesizes high quality long RNA of >100 nt. The ability to synthesize longer RNA oligos is highly sequence-dependent due to the potential for secondary structure formation and the inherent difficulty for chemical synthesis of certain sequences. Reduced yield is possible as oligo length increases. We also offer enzymatic RNA synthesis by transcription up to thousands of bases in length using DNA template.
