Natural safety
Chlamydomonas reinhardtii is a natural edible alga for human beings. Due to its special structural cells, rapid growth, clear genetic background and easy transformation, it has become an emerging model species for studying gene function, foreign gene expression and biological hydrogen production. It is called "green yeast" and "photosynthetic yeast". In 2019 and 2022, it has been recognized and approved by the US Food and Drug Administration and the China's National Health Commission of China for direct consumption, and its metabolites do not contain toxic substances such as endotoxin.
active protein
Chlamydomonas reinhardtii has unique evolutionary characteristics that are shared by both animals and plants. It possesses various post-translational modifications of proteins, resulting in recombinant protein products with background source activity. The genetic operation system of Chlamydomonas reinhardtii cells is perfect, which can efficiently screen recombinant protein drugs.
Targeted precision
The Yuanqi Hesheng team obtained highly efficient expression of recombinant hirudin in Chlamydomonas reinhardtii cell lines through large-scale screening, and demonstrated from a biochemical perspective that sulfation modification of the 63rd tyrosine residue of the recombinant hirudin protein from Chlamydomonas reinhardtii can effectively help inhibit thrombin, reduce total cholesterol, triglycerides, and other conditions.
