EZ Biosystems' custom recombinant protein services provide a comprehensive portfolio of protein expression systems, from bacteria to mammalian cells. With our proprietary Codon Optimization Technology, the expression level of target proteins can be significantly increased in most systems, especially in E. coli system. In addition, we offer a full spectrum of protein purification methods to achieve the ideal level of protein purity for your downstream applications. With customized solutions, flexible production scale, and proprietary technologies, we work in partnership with our clients to ensure efficient and high quality reagent protein production, process development and scale-up production of biologics for research purposes.


We provide risk-free trial for clients:  Just send DNA sequences to us, we'll take care of the rest. Our dedicated technical account managers will guide your project through every step of the process, and constantly keep you informed of the project progress.




  1. Comprehensive expression systems: from Bacteria to mammalian cell plus various vectors for each system.
  2. Fast turnaround: We are able to delivers 10 mg of purified protein in as little as 4 weeks merely from your submitted target gene sequence.
  3. Bioprocess services: Significantly increase the expression level of your target protein to gram level by carrying out stable cell line construction and process development.
  1. One-stop service platform: EZ Biosystems can take your project directly from gene synthesis, to any of those further stages including recombinant protein expression, stable cell line generation, antibody production, and assay development.
