Abstract

Polypeptides with desirable biophysical properties such as solubility, stability, high expression, monomericity, binding specificity or non-aggregation, including monomeric human Vs and Vs, are identified using a high throughput method for screening polypeptides, comprising the steps of obtaining a phage display library, allowing infection of a bacterial lawn by the library phage, and identifying phage which form larger than average plaques on the bacterial lawn. Sequences of monomeric human Vs and Vs are identified, which may be useful for immunotherapy or as diagnostic agents. Multimer complexes of human Vs and Vs are also identified. The Vs and Vs identified may be used to create further libraries for identifying additional polypeptides. Further, the Vs and Vs may be subjected to DNA shuffling to select for improved biophysical properties.
