Abstract

Screening of specific phage is often hampered by nonspecific binding either of the VCS M13 helper phage to the solid phase absorbent or to the polyclonal antibodies used for selection. The former is improved by increasing the stringency for selection. However, the available polyclonal anti-VCS M13 antibodies often react with immobilized antigen nonspecifically, making it difficult to distinguish between positive and negative clones. To improve this selection process, a monoclonal antibody (MAb) was produced which recognizes ligand-coat protein three (gIIIp) on the helper phage VCS M13. This MAb is highly sensitive and specific, and it is useful for selecting relevant clones. This reagent should find widespread application in identifying interactive clones from a variety of phage display libraries.
