In the past decades, monoclonal antibodies have made an unprecedented transformation from research tools to a rapidly growing class of therapeutics. Advancements in the yeast surface display platform enable the selection of favorable mouse or human antibody variants from large B-cell receptor (BCR) gene repertoires that are derived from immunized normal or transgenic animals. Application of high-throughput fluorescence-activated cell sorting (FACS) screening along with well-chosen selection settings can be utilized to identify variants with desired affinities and predefined epitope binding properties. In the following chapter, we describe in detail a multiparameter screening protocol for the selection of antibody variants from yeast libraries generated from BCR gene repertoires from immunized transgenic rats. The procedure provides guidance for the selection of antigen-specific, high-affinity binding, and species cross-reactive human antibodies with a broad epitope coverage. Essentially, this can accelerate target-specific antibody characterization as multiple desirable antibody features can be easily integrated into the selection procedure. In addition, we provide information on how to validate binding behavior of selected candidates after expression as soluble, full-length IgG molecules.
