The Importance of High-Purity Functional RNA

The successful outcome of RNA applications, particularly in gene knockdown ( siRNA ) and CRISPR gene editing ( sgRNA ), relies heavily on the quality and purity of the synthesized molecule. Impurities or truncated sequences can lead to off-target effects, toxicity, or inefficient delivery. Our synthesis protocols prioritize high-yield solid-phase synthesis followed by stringent HPLC or PAGE purification to remove contaminating species. Furthermore, our ability to introduce Custom RNA Modifications dramatically enhances the stability and in vivo efficacy of therapeutic RNA constructs.

FAQs about Custom RNA Synthesis Services

Still have questions?

Contact Us

What is the typical purity level for your functional RNAs ( siRNA, sgRNA )?

For functional RNAs like siRNA and sgRNA ( CRISPR-Cas9 sgRNA Synthesis ), we guarantee a minimum purity of >95% , achieved via HPLC purification, which is essential to eliminate impurities that cause off-target effects.

What is the advantage of using Custom RNA Modifications ?

Modifications, such as 2'- O - Methyl or Phosphorothioate bonds , significantly increase the nuclease resistance and serum half-life of RNA (e.g., siRNA or miRNA Agomir ), making them suitable for in vivo therapeutic studies.

Can you synthesize RNA transcripts longer than 100 bases?

Yes, our Long RNA Synthesis Service utilizes optimized in vitro transcription ( IVT ) to produce high-yield mRNA or long non-coding RNA ( lncRNA ) transcripts in milligram to gram quantities.

How do you ensure the quality of sgRNA libraries?

Our Custom sgRNA Libraries (including Human Genome Knockout Libraries ) are synthesized with high uniformity and minimal bias, and the final quality is confirmed via Next - Generation Sequencing ( NGS ) analysis.

How much does Metabolic Engineering services cost?

The cost of Metabolic Engineering services depends on the project scope, complexity of the target compound, the host organism chosen, and the required yield optimization. We provide customized quotes after a detailed discussion of your specific research objectives.

Do your engineered strains meet regulatory standards?

We adhere to high quality control standards in all strain construction and optimization processes. While we do not handle final regulatory approval, our detailed documentation and compliance with best laboratory practices ensure your engineered strains are prepared for necessary regulatory filings (e.g., GRAS , FDA ).

What to look for when selecting the best gene editing service?

We provide various gene editing services such as CRISPR-sgRNA library generation, stable transformation cell line generation, gene knockout cell line generation, and gene point mutation cell line generation. Users are free to select the type of service that suits their research.

Does gene editing allow customisability?

Yes, we offer very customised gene editing solutions such as AAV vector capsid directed evolution, mRNA vector gene delivery, library creation, promoter evolution and screening, etc.
