The yeast protein expression system is the most economical and efficient eukaryotic system for intracellular expression and secretion. A protein expressed by the mammalian cell system is of very high quality and close to the natural protein. But the low level of expression, the high cost of the medium and the culture conditions restrict the promotion of mammalian cell expression systems. The N-terminal 6xHis-KSI-tagged Recombinant yeast protein expression system serves as a eukaryotic system that integrates the advantages of the mammalian cell expression system.

A protein expressed by a yeast system could be modified by glycosylation, acylation, phosphorylation, etc., to ensure the conformation of the native protein. It can be used to produce protein material with high added value that is very close to the natural protein. Our proteins produced by the yeast expression system have been used as starting material for the subsequent preparation of monoclonal antibodies.
