Overview Service Process Examples and Solutions Applications Frequently Asked Questions


Fusion proteins are engineered molecules that combine sequences from two or more different proteins to create a single, multifunctional protein. These fusion constructs can facilitate protein purification, improve stability, enhance biological activity, or enable targeted delivery. Our services encompass the entire process of producing fusion proteins, leveraging state-of-the-art technologies and expertise to deliver high-quality, functional proteins for your applications.

Service Process

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

  1. Gene Synthesis and Cloning: Designing and synthesizing the gene encoding the fusion protein, followed by cloning into an appropriate expression vector. This step includes verification through sequencing to ensure accuracy.
  2. Expression Vector Construction: Constructing expression vectors tailored to the host system, whether bacterial, yeast, insect, or mammalian cells. This ensures optimal expression of the fusion protein.
  3. Protein Expression: Introducing the expression vector into the chosen host system and optimizing conditions to maximize protein expression. This may involve adjusting parameters such as temperature, inducer concentration, and growth media.
  4. Protein Purification: Isolating the fusion protein from the 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 fusion protein.
  5. Characterization and Validation: Assessing the purity, stability, and functionality of the fusion protein using methods such as SDS-PAGE, Western blotting, mass spectrometry, and activity assays. This ensures that the fusion protein meets the desired specifications.
  6. 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.
