Recombinant Protein Development Platform
Recombinant proteins have different biological activities and are widely used in different fields of biological research and development. Our company provides comprehensive services for biopharmaceutical companies and scientific research institutions to develop recombinant proteins for rare diseases. Our recombinant protein development platform offers multiple advantages, including expertise, customization, high-quality products, fast turnaround times, competitive pricing, confidentiality, and regulatory compliance.
Introduction to Recombinant Proteins
Recombinant protein production is a protein obtained by applying recombinant DNA or recombinant RNA technology. The production of recombinant proteins in vitro mainly includes four major systems: E. coli expression system, mammalian expression system, yeast expression system, and insect expression system. Choose an appropriate protein expression system based on your downstream application to improve the expression success rate. Recombinant proteins can be divided into the following types according to their functions:
- Interleukin (IL)
- Interferon (IFN)
- Tumor necrosis factor (TNF)
- Colony stimulating factor (CSF)
- Growth factor (GF)
- Chemokine

Applications of Recombinant Proteins
Based on different expression systems, recombinant proteins are used in different fields:
- Prophylactic recombinant protein vaccine
- Development of diagnostic reagents
- Enzyme preparation
- Immune checkpoints
- Antibody-drug targets
- CAR-T cell therapy targets
- Fc receptors
- Influenza viral proteins
- Cytokines
- Immunodetection reagents
- Protein based drugs
