•CAStar's core technology involves using Kluyveromyces marxianus yeast as a chassis cell for genetic engineering to express and secrete glycosylated exogenous proteins. The company employs high-throughput screening to obtain high-expression cell strains for large-scale precision fermentation. Their focus is on producing glycoproteins similar to human milk proteins, which offer immune, antibacterial, and antioxidant benefits. CAStar has developed portfolios of expression vectors and chassis cells, enabling rapid selection for genetic editing to express desired proteins.
