Gene Editing mRNA Synthesis Service
In the rapidly evolving landscape of genomic medicine, messenger RNA (mRNA) has emerged as a cornerstone for delivering gene editing tools. Unlike DNA-based delivery methods, mRNA offers a transient, non-integrating, and highly efficient approach to expressing site-specific nucleases and editors. At CD BioGlyco, we provide a specialized gene editing mRNA synthesis service designed to support researchers in navigating the complexities of modern genome engineering. We produce high-purity mRNA encoding a variety of editing enzymes, from classical gene editing-associated proteins to sophisticated base and prime editors.
Our service is meticulously integrated into our therapeutic nucleic acid development platform, ensuring that every transcript is optimized for stability, translation efficiency, and reduced immunogenicity. Whether your goal is to knock out a disease-causing gene, correct a point mutation, or engineer complex cellular traits, CD BioGlyco delivers the high-quality genetic material required to achieve consistent and reproducible results in both in vitro and in vivo systems.
Key Technologies
- Advanced In Vitro Transcription (IVT)
We utilize high-fidelity T7 RNA polymerases and optimized buffer systems to minimize the production of double-stranded RNA (dsRNA) by-products. This reduces the activation of innate immune sensors, ensuring that the gene editing mRNA remains functional within target cells.
- Precision 5' Capping and 3' Polyadenylation
We employ both enzymatic and co-transcriptional capping strategies to ensure a natural Cap-1 structure. Coupled with precise poly(A) tail length control, our transcripts exhibit enhanced half-lives and protein expression levels.
- Nucleoside Modification Strategy
We offer comprehensive chemical modifications, such as the incorporation of N1-methylpseudouridine (m1ψ) or 5-methoxyuridine (5moU), which have been proven to significantly enhance the safety profile of therapeutic mRNA.
Precision Gene Editing mRNA Synthesis for Next-Generation Genome Engineering
As a specialized component of our therapeutic oligonucleotide synthesis service, CD BioGlyco provides a comprehensive range of mRNA synthesis options tailored specifically for gene editing applications. Our scope includes:
- Standard and Engineered Cas Nucleases: Synthesis of mRNA encoding widely used nucleases, as well as high-fidelity variants designed to minimize off-target effects.
- Base and Prime Editors: Production of complex fusion proteins, including cytidine base editors (CBE) and adenine base editors (ABE), which enable precise single-nucleotide changes without inducing double-strand breaks (DSB). We also support the synthesis of prime editor (PE) mRNA for "search-and-replace" genome editing.
- Custom Sequence Optimization: Our experts provide codon optimization and untranslated region (UTR) engineering to maximize the expression of gene editing tools in specific cell types or species.
- Multiplexing and Co-delivery Solutions: Synthesis of multiple mRNA species for complex engineering tasks, ensuring batch-to-batch consistency and optimal purity for combined delivery.
Workflow
Sequence Design and Codon Optimization
We begin by analyzing the target enzyme sequence. Utilizing proprietary algorithms, we optimize codons and secondary structures to enhance translational efficiency and avoid premature degradation, ensuring the mRNA performs optimally in your target organism.
DNA Template Construction and Linearization
High-purity plasmid DNA (pDNA) templates are synthesized or prepared. The pDNA is then precisely linearized using restriction enzymes to provide a clear termination point for the IVT process, ensuring the production of uniform, full-length transcripts.
IVT Reaction
The linearized template undergoes transcription in a controlled environment. We monitor the reaction parameters closely to maximize yield while maintaining the integrity of the nascent mRNA molecules and minimizing truncated fragments.
Post-Transcriptional Capping and Tailing
Following transcription, the mRNA undergoes capping and polyadenylation. This step is critical for protecting the mRNA from exonucleases and ensuring it is recognized by the cell's ribosomal complex for immediate protein synthesis.
Multi-Step Purification
We use advanced purification techniques, including high-performance liquid chromatography (HPLC) and tangential flow filtration (TFF), to remove residual DNA, enzymes, and immunogenic dsRNA, resulting in a highly pure final product.
Comprehensive Quality Control (QC)
Every batch undergoes rigorous QC testing, including fragment analysis for integrity, sequence verification, endotoxin testing, and purity assessment via capillary electrophoresis (CE), ensuring the mRNA meets the highest research standards.

Results: This article focuses on optimizing in vitro mRNA synthesis via T7 RNA polymerase (T7 RNAP) to reduce impurities, especially immunogenic dsRNA. The authors found that the G753A mutation in T7 RNAP's specificity loop cuts dsRNA production to 17.76±1.37% by weakening non-specific binding and lowering antisense RNA levels, without reducing mRNA yield. Combining G753A with modified nucleotide m1ψTP further drops dsRNA to <3%. Though G753A increases fragmented mRNA, adding the K389A mutation (known for high mRNA integrity) restores mRNA integrity to wild-type levels while maintaining low dsRNA. This cost-effective strategy of engineered T7 RNAP (G753A+K389A) with m1ψTP enables high-purity, low-immunogenicity mRNA synthesis, aiding mRNA therapeutic development.
