Recombinant Protein Expression Type Applications Description
Bacterial Expression Systems - Biopharmaceuticals, industrial enzymes, protein production for research. - Description: Utilizes bacterial cells, such as E. coli, for the expression of recombinant proteins. Bacterial systems are often chosen for their simplicity, rapid growth, and cost-effectiveness. However, they may lack post-translational modifications present in eukaryotic cells.
Yeast Expression Systems - Production of eukaryotic proteins, industrial enzymes, vaccine antigens. - Description: Utilizes yeast cells, such as Saccharomyces cerevisiae or Pichia pastoris, for the expression of recombinant proteins. Yeast systems offer eukaryotic protein folding and post-translational modifications, making them suitable for certain applications requiring native-like protein structures.
Mammalian Expression Systems - Production of therapeutic proteins, antibodies, and proteins requiring complex post-translational modifications. - Description: Utilizes mammalian cells, often human or CHO (Chinese Hamster Ovary) cells, for the expression of recombinant proteins. Mammalian systems provide native-like post-translational modifications, making them suitable for the production of therapeutic proteins and complex biologics.
Insect Cell Expression Systems - Production of eukaryotic proteins, vaccine antigens, virus-like particles. - Description: Utilizes insect cells, often derived from baculoviruses, for the expression of recombinant proteins. Insect cell systems offer advantages of eukaryotic protein folding and post-translational modifications, making them suitable for certain applications, especially when mammalian systems are not feasible.
