EastMabBio

High-Quality Recombinant Proteins

EastMabBio was founded in 2016 and is a global manufacturer of high-quality recombinant proteins. Its comprehensive portfolio includes cytokines, growth factors, antigens, antibodies, and other complex proteins, covering a wide range of applications—from basic research in the life sciences to cutting-edge fields such as stem cell therapy, immune cell therapy, organoid research, regenerative medicine, and cellular agriculture.

 

EastMabBio proteins are distinguished by the following:

  • CHO expression: Most proteins are expressed in CHO cells, which ensures proper protein folding and native post-translational modifications. CHO-cell-based production also offers excellent stability, scalability, and a proven safety profile.
  • IP-Licensed Host: The authorized CHO-K1 cell line ensures complete IP traceability, clear rights for commercial use, and comprehensive support for documentation.
  • Tag-Free Design: Most proteins are engineered without tags to better preserve native protein structure and function while reducing potential immunogenicity concerns.

 

Product Range:

  • Cytokines and growth factors (RUO/GMP quality)
  • Extracellular matrix proteins
  • Antigens and antibodies
  • Cell culture kits
