Yeast display Platform

Yeast surface display is a eukaryotic protein expression system. It is a high-throughput screening method for screening protein mutant libraries. It is widely used in research on antibody expression, in vitro maturation and screening, and has high efficiency, Sensitive and other characteristics. The basic principle is to fuse the exogenous target gene with a specific carrier gene sequence and then introduce it into the yeast cell, and use the yeast cell protein transport mechanism to transfer the target protein to the cell surface and fix it on the cell membrane.

Compared with traditional phage display technology, the yeast surface display system is a new method that combines random mutagenesis and combinatorial libraries to screen peptides and proteins with specific properties. It can avoid the phage itself and the target protein. Non-specific binding is an important supplement to the phage surface display system.

Application of Yeast Display Technology in SdAb Preparation :

In the process of obtaining sdAb using the yeast display system, we display the sdAb on the surface of the yeast, and after sorting the positive clones by FACS, we can obtain diverse antibody sequences by sequencing. This method can perfectly simulate the structure of all sdAb on the cell membrane surface, correctly reflect the binding of sdAb to antigens, and rarely occur non-specific binding of phage display libraries. In addition, the yeast display library technology also has more cost advantages when carrying out multiple sdAb screening work.
