Abstract

Antibody phage display selection on cells is a powerful tool to generate highly specific antibodies recognizing a target in its cell bound conformation. Unlike phage display selections on immobilized proteins, it is not hampered by difficulties caused by recombinant protein expression of target proteins like altered folding or loss of epitopes. It also allows the generation of antibodies against proteins that are commercially unavailable, due to high production costs or lack of production. It is also a promising approach for single and especially multi-pass membrane proteins for which the complex secondary and tertiary structures can often not be retained upon recombinant protein expression. The selected antibodies are not only tools for in vivo studies but also used for the development of diagnostic assays and for therapeutical applications. Here, we describe a straightforward protocol for generation and screening of scFv binders by phage display selections on cells.
