Meet your various RNA projects

Both unmodified and modified RNA oligos / Comprehensive backbones

Flexible synthesis scales / High-quality and cost-effective

Custom RNA Oligos

Synthetic RNA is widely used in research applications as an important tool for gene functional analysis and the development of novel therapeutic strategies. GenScript provides high-quality and cost-effective custom RNA oligos with flexible synthesis scales to meet researchers' different needs. Unmodified RNA, RNA with modifications, chimeric oligonucleotides with mixed DNA and RNA bases, 2'-OMe-RNA, 2'-F-RNA, and other antisense RNAs are available at your specific request. To ensure that the RNA oligos are of highest quality, all RNA oligonucleotides are identified by ESI (electrospray ionization) mass spectrometry. To meet QC specifications, the deviation from measured mass to calculated mass must be no more than 1‰. The purity of the RNA is analyzed by HPLC.
