Methods for Custom Protein Production

Method Description Applicable Scenarios
Bacterial Expression Systems Utilizes bacteria, typically E. coli, to express recombinant proteins due to their rapid growth and high yield capabilities. Suitable for producing large quantities of protein quickly and cost-effectively, ideal for initial screening and large-scale production.
Yeast Expression Systems Employs yeast cells, such as Saccharomyces cerevisiae or Pichia pastoris, for protein expression, offering eukaryotic post-translational modifications. Useful for producing proteins with complex post-translational modifications, such as glycosylation, suitable for both research and industrial applications.
Insect Cell Expression Systems Uses baculovirus-infected insect cells (e.g., Sf9, Sf21) to produce recombinant proteins with proper eukaryotic folding and modifications. Ideal for producing proteins that require complex post-translational modifications and proper folding, often used in structural biology and vaccine production.
Mammalian Cell Expression Systems Involves the use of mammalian cell lines (e.g., HEK293, CHO) to produce proteins with native folding and human-like post-translational modifications. Essential for producing therapeutic proteins, antibodies, and proteins requiring human-like modifications, widely used in pharmaceutical development.
Cell-Free Expression Systems Employs cell-free extracts to synthesize proteins in vitro, offering rapid and scalable protein production without the need for living cells. Suitable for rapid protein production, high-throughput screening, and situations where toxic or unstable proteins are produced.
Transient Expression Systems Involves the temporary expression of proteins in cells, allowing for rapid production without the need for stable cell line development. Useful for quick production of proteins for preliminary studies, functional assays, and small-scale experiments.
Stable Cell Line Development Generates cell lines that stably express the protein of interest, ensuring consistent and long-term protein production. Ideal for large-scale and long-term production of therapeutic proteins, monoclonal antibodies, and other biopharmaceuticals.
Fusion Protein Expression Utilizes fusion tags (e.g., His-tag, GST-tag) to enhance the solubility and facilitate the purification of recombinant proteins. Suitable for simplifying protein purification processes, improving yield, and enabling easy detection and quantification.
Multigene Expression Systems Allows for the simultaneous expression of multiple proteins, enabling the production of protein complexes and pathways in a single host. Ideal for studying protein-protein interactions, metabolic engineering, and producing multi-subunit complexes.

Each method in custom protein production is chosen based on the specific requirements of the target protein, such as the need for post-translational modifications, yield, speed, and the intended application. The flexibility in choosing the appropriate system ensures the efficient and effective production of high-quality recombinant proteins.

Service Process

The process of custom protein production involves several critical and interrelated steps:

  1. Project Consultation: Collaborating with clients to define specific protein production requirements, including target protein function, expression system, and purification needs.
  2. Gene Synthesis and Cloning: Designing and synthesizing the gene encoding the target protein, followed by cloning into an appropriate expression vector. Verification through sequencing ensures accuracy.
  3. Expression Vector Construction: Constructing expression vectors tailored to the selected host system (bacterial, yeast, insect, or mammalian cells) to achieve optimal protein expression.
  4. Protein Expression: Introducing the expression vector into the chosen host system and optimizing conditions to maximize protein yield. Parameters such as temperature, inducer concentration, and growth media are adjusted.
  5. Protein Purification: Isolating the expressed protein from host cells using techniques such as affinity chromatography, size-exclusion chromatography, or ion exchange chromatography. Purification strategies are tailored to the specific properties of the protein.
  6. Characterization and Validation: Assessing the purity, stability, and functionality of the expressed protein using methods such as SDS-PAGE, Western blotting, mass spectrometry, and activity assays.
  7. Optimization and Scale-Up: Refining the production process based on initial results and scaling up production to meet the required quantities for research or commercial use.
