Biosynthesis of foreign proteins using transformed microalgae

摘要

The present invention relates to an economical method for biosynthesis of intended foreign proteins using transformed microalgae, that is to say, it relates to a method of using transformed microalgae as a bioreactor where economical biosynthesis of foreign protein is possible by transforming protoplast of microalgae such as iChlorella ellipsoidea/i with DNA vector containing intended foreign protein gene and then culturing it in a large scale. In particular, Sh ble gene, which is resistant to phleomycin, is used as a selection marker in the present invention.
