Get a QuoteEfficient industrial production in C. glutamicum relies on precise manipulation of its central metabolism and regulatory networks. Traditional engineering methods in this host often suffer from low efficiency and difficulty in performing sequential edits. Our optimized CRISPR-Cas9 system overcomes these limitations by offering high-precision, multiplex editing capabilities. This technology allows for the targeted inactivation of competing pathways, the introduction of heterologous production routes, and the tuning of native regulatory genes. By focusing on rapid turnaround and rigorous sequence verification, we ensure the stability and reliability of the final engineered strains, providing the necessary genetic tools for maximizing the production of desired amino acids and chemicals.

Why is CRISPR-Cas9 preferred over traditional methods for C. glutamicum?
CRISPR-Cas9 significantly boosts editing efficiency, especially for sequential and multiplex edits, which are notoriously difficult with the native, less efficient homologous recombination pathways in C. glutamicum.
Can you perform marker-free gene knockouts?
Yes. Our optimized protocol includes steps for efficient removal (curing) of the Cas9-containing plasmid and removal of any temporary selection markers, delivering a clean, marker-free genome.
How do you verify the sequence of the edited locus?
Every single edited locus (knockout, knock-in, or point mutation) is verified by PCR analysis and subsequent Sanger Sequencing across the entire modified region to guarantee 100% sequence accuracy.
Are you able to perform multiplex editing (multiple genes at once)?
Yes, we offer multiplex editing, which allows for the simultaneous modification of multiple genes (e.g., up to 4-5) in a single cycle, accelerating the construction of complex metabolic strains.
What is the main application of Base Editing in C. glutamicum?
Base Editing is ideal for precision enzyme engineering, allowing single base pair changes to modify enzyme activity, alter allosteric sites, or tune promoter strength without causing double-strand breaks.
Can you integrate large DNA fragments, such as heterologous pathways?
Yes. Our CRISPR-assisted Gene Knock-in service is optimized for the stable chromosomal integration of large biosynthetic gene clusters or heterologous pathways (up to several kb).
What safety features are implemented to prevent off-target effects?
We use state-of-the-art bioinformatics tools for sgRNA design to select targets with the lowest off-target potential, and our final sequence verification confirms only the desired edit has occurred.
What are the deliverables for a standard editing project?
The final deliverables include the fully verified engineered C. glutamicum strain, a detailed Certificate of Analysis (CoA), and all raw sequencing data supporting the modification.
CRISPR-Cas9 technology represents a transformative advancement in gene editing techniques. The main function of the system is to precisely cut DNA sequences by combining guide RNA (gRNA) with the Cas9 protein. This technology became a mainstream genome editing tool quickly after its 2012 introduction because of its efficient, simple and low-cost nature.
The CRISPR gene editing system with its Cas9 version stands as a vital instrument for current biological research. CRISPR technology enables gene knockout (KO) through permanent gene expression blockage achieved by sequence disruption. Various scientific domains including disease modeling and drug screening employ this technology to study gene functions. CRISPR KO technology demonstrates high efficiency and precision but requires confirmation and verification post-implementation because unsatisfactory editing may produce off-target effects or incomplete gene knockouts which impact experimental result reliability. For precise and efficient Gene Editing Services - CD Biosynsis, Biosynsis offers comprehensive solutions tailored to your research needs.
The CRISPR-Cas9 knockout cell line was developed using CRISPR/Cas9 gene editing to allow scientists to remove genes accurately for research on gene function and disease models and pharmaceutical discovery. Genetic research considers this technology essential due to its high efficiency together with simple operation and broad usability.
