| Abstract: | "The described protocols enable thorough screening of polypeptide libraries with high confidence in the isolation of improved clones. It should be emphasized that the protocols have been fashioned for thoroughness, rather than speed. With library plasmid DNA in hand, the time to plated candidate yeast display mutants is typically 2-3 weeks. Each of the experimental approaches required for this method is fairly standard: yeast culture, immunofluorescent labeling, flow cytometry. Protocols that are more rapid could conceivably be developed by using solid substrate separations with magnetic beads, for instance. However, loss of the two-color normalization possible with flow cytometry would remove the quantitative advantage of the method. Yeast display complements existing polypeptide library methods and opens the possibility of examining extracellular eukaryotic proteins, an important class of proteins not generally amenable to yeast two-hybrid or phage display methodologies" |
