Abstract

Objectives

Develop a Cell Surface Display system in Saccharomyces cerevisiae, based on the construction of an expression cassette for pYES2 plasmid.

Results

The construction of an expression cassette containing the α-factor signal peptide and the C-terminal portion of the α-agglutinin protein was made and its sequence inserted into a plasmid named pYES2/gDαAgglutinin. The construction allows surface display of bovine herpesvirus type 5 (BoHV-5) glycoprotein D (gD) on S. cerevisiae BY4741 strain. Recombinant protein expression was confirmed by dot blot, and indirect immunofluorescence using monoclonal anti-histidine antibodies and polyclonal antibodies from mice experimentally vaccinated with a recombinant gD.

Conclusions

These results demonstrate that the approach and plasmid used represent not only an effective system for immobilizing proteins on the yeast cell surface, as well as a platform for immunobiologicals development.
