Yeast display is a eukaryotic protein expression technology that uses a yeast surface display system which has a complete protein post-translational modification and secretion mechanism to immobilize and display heterologous eukaryotic proteins on the surface of yeast. At present, yeast display technology has been widely used in many fields such as protein library screening, protein directed evolution, high affinity antibody sorting, antigen/antibody library construction, affinity maturation, vaccine production, immune biocatalysis, and biosensors.
The principle of yeast cell surface display technology:
The exogenous target protein gene sequence (such as a single domain antibody) is fused with a specific vector gene sequence and then introduced into yeast cells, and then the target protein is expressed and localized on the yeast cell surface by using the yeast cell intracellular protein transport mechanism (GPI anchoring).

Nowadays, yeast display system has been widely used in directed evolution of protein. Profacgen provides display platforms including Pichia pastoris and Saccharomyces cerevisiae, and provides services such as protein expression purification, expression kinetic analysis, etc., which can be used for in vitro discovery and design of high-efficiency antibody candidates for therapy or diagnosis.
