Expression System

ICE Bioscience's Protein Science Department provides high-quality custom protein services to meet the various needs of the scientific and industrial communities. Each project has different requirements for proteins, so the Protein Science Department uses three common protein expression systems: E. coli expression system, insect cell expression system, and mammalian cell expression system, to ensure optimal expression and functional activity of each protein during production. Whether you need large-scale production of high-purity recombinant proteins or small quantities of high-activity functional proteins, we can tailor solutions to your needs. We are always customer-focused and committed to providing the best products and services to help our customers achieve breakthrough progress in research and industry.

Customized precision, achieving scientific research—your expert in protein expression!



  • E.coli

    Clear background, non-toxic
    Simple operation, easy for large-scale production
    Low cost, suitable for industrial production and basic research
    Rapid growth cycle and efficient protein expression capacity

  • Insect cells

    Baculovirus only infects insect cells, ensuring safety
    Suitable for expressing proteins with large molecular weights
    Capable of achieving high protein expression levels, meeting the needs of high-yield production
    Able to express proteins with complex folding and post-translational modifications, achieving expression effects similar to mammalian cells

  • Mammalian cells

    Capable of complex post-translational modifications including glycosylation and phosphorylation, making the expressed proteins closer to their natural state
    The expressed proteins have high biological activity, suitable for functional research and biopharmaceutical production
    Suitable for expressing complex proteins, secreted proteins, or extracellular domains
