Yeast Display Technology Platform

Yeast surface display (YSD) is a powerful protein engineering technology and an important high-throughput screening platform in protein engineering. Yeast cells have eukaryotic post-translational modification mechanisms that can help target proteins fold correctly and can be used to display various eukaryotic proteins, including antibodies, receptors, enzymes, and antigenic peptides.


Technical Principle

The AlpVHHs yeast surface display platform uses the "α-lectin" display system to insert the nanobody gene sequence and the expression tag HA tag gene sequence into the display plasmid vector of the protein scaffold-Aga2 gene. The vector uses nutritional markers to maintain selective growth in yeast, and galactose is added to the culture medium to induce yeast to display on the surface. The nanobody fusion protein is secreted and anchored on the yeast cell wall. Combined with magnetic beads and flow sorting technology for multiple rounds of screening, high-affinity and high-stability clones can be screened.


Yeast Display Technology Platform


Advantages of yeast display:

1. Eukaryotic expression system can ensure the true folding of proteins

2. Uniform growth of yeast reduces screening bias

3. Screening can be refined through flow sorting, such as affinity screening, blocker, epitope screening, etc.

4. Compatible with NGS, convenient for obtaining a large amount of post-selection information
