Long RNA Oligo Synthesis Services
Synthetic RNA occupies a very special place in modern research. Custom solid-phase synthesis of 20-30 nucleotide-long strands has become a powerful driving force in many fields of biochemical and pharmaceutical research. Discoveries of the twenty-first century created a strong need for a robust solid-phase synthesis of longer RNA strands, over 100 nucleotides (-nt) in length[1]. Long RNA oligonucleotides are increasingly important in genomic function studies, drug discovery research and biosynthesis. In recent years, with the remarkable progress of RNA-related research, the demand for long-chain RNA is increasing. However, the chemical synthesis and purification of long-chain RNA (>50mer) face unique challenges due to their sequence composition, secondary structure and modifications.
Although several ingenious strategies have been developed to minimize these problems and to improve the synthesis of long RNA, the chemical complexity of solid-phrase RNA synthesis dictates that constructs longer than 50 nucleotides in length remain difficult to prepare. Most biologically important RNA molecules such as ribozymes, aptamers, and riboswitches are significantly longer than this, so new approaches to synthesize RNA analogs are urgently required.
Although RNA synthesis by transcription might seem a viable alternative, it does not allow the site-specific incorporation of multiple modifications at sugars, bases, or phosphates. In contrast, automated solid-phase RNA synthesis is compatible with the introduction of fluorescent tags, isotopic labels (for NMR studies) and other groups to improve biological activity and resistance to enzymatic degradation. The scope and utility of important RNA constructs can be significantly extended by such chemical modifications, and the scale of chemical synthesis is potentially unlimited. These are important factors when planning structural studies on RNA or the development of therapeutic oligoribonucleotides analogs, and should be considered when devising new methods of RNA assembly[2].

Purification
When the length of oligos increases, there are more deletions in the oligonucleotide sequence. Therefore, we strongly recommend using polyacrylamide gel electrophoresis(PAGE) to purify oligonucleotides of more than 50 bases.
Purified by PAGE, its purity can reach 97%~99.9%.
