Abstract
Yeast surface display (YSD) is an ultra-high throughput method used in protein engineering. Protein-protein interactions as well as surface presentation on the yeast cell surface are verified through fluorophore-conjugated labeling agents.
In this chapter we describe an improved setup for full-length surface presentation detection. To this end, we used a single open reading frame (ORF) encoding for the protein to be displayed and a 2A sequence and tGFP for an intracellular fluorescence signal. The 2A sequence allows the simultaneous generation of two separate proteins from the same ORF through ribosomal skipping. The entangled expression of the POI on the yeast surface and intracellular tGFP obviates the need for fluorescent staining steps.
