Overview Service Process Examples and Solutions Frequently Asked Questions


Multigene expression systems involve the introduction and regulation of multiple genes within a single organism, enabling the study and manipulation of complex biological pathways. These systems are essential for applications requiring the co-expression of several proteins, such as metabolic pathway engineering, protein complex assembly, and synthetic biology constructs. Our services leverage advanced genetic engineering techniques to deliver high-quality multigene expression systems.

The experimental method process generally includes the following steps:

  1. Choose the appropriate expression vector: Choose a vector that is suitable for expressing multiple genes, such as multi clone vectors, peptide chain expression vectors, etc.
  2. Cloning target genes: Clone multiple genes that need to be expressed into the selected expression vector in sequence.
  3. Transfected cells: transfect the constructed multi gene expression vector into the target host cell.
  4. Screening positive cell lines: Through appropriate antibiotic screening, select cell lines that successfully express the target gene.
  5. Validation of expression: Verify the expression level of the target gene in cells through methods such as RT-PCR and Western blot.
  6. Functional analysis: Conduct functional experiments on cells expressing multiple genes, studying the interactions and regulatory networks between multiple genes.

The above is the general experimental method flow of Multigene expression systems, which needs to be optimized and adjusted according to specific research objectives and experimental conditions during the experimental process.

Service Process

The process of developing multigene expression systems involves several critical and interrelated steps:

  1. Project Consultation: Collaborating with researchers to define specific multigene expression requirements, including the target genes, desired expression levels, and intended applications.
  2. Vector Design and Construction: Designing and constructing expression vectors that allow for the simultaneous and coordinated expression of multiple genes. This includes selecting appropriate promoters, regulatory elements, and vector backbones.
  3. Host Strain Selection: Choosing the most suitable host organism for multigene expression, such as bacteria, yeast, plant cells, or mammalian cells.
  4. Transformation/Transfection: Introducing the multigene constructs into the host cells using transformation or transfection techniques to achieve stable or transient expression.
  5. Selection and Screening: Selecting successfully transformed cells using selectable markers and screening for the expression of all target genes.
  6. Optimization: Optimizing expression conditions to ensure balanced and high-level expression of all genes. This may include adjusting growth conditions, inducer concentrations, and optimizing codon usage.
  7. Characterization and Validation: Characterizing the expression system to confirm the presence, expression levels, and functionality of all genes using methods such as qPCR, Western blotting, and functional assays.
  8. Scale-Up and Production: Scaling up the multigene expression system for large-scale production and further applications in research or industry.
  9. Reporting and Consultation: Providing a detailed report of the findings and offering further consultation to interpret the results and plan subsequent research steps.
