Antibody Isolation From a Human Synthetic Combinatorial and Other Libraries of Single-Chain Antibodies.

ABSTRACT

Antibody libraries came into existence 25 years ago when the accumulating sequence data of immunoglobulin genes and the advent of the PCR technology made it possible to clone antibody gene repertoires. Phage display (most common) and additional display and screening technologies were applied to pan out desired binding specificities from antibody libraries. "Synthetic" or "semisynthetic" libraries are from naive-non-immunized source and considered to be a source for many different targets, including self-antigens.As other antibody discovery tools, phage display is not an off-the-shelf technology and not offered as a kit but rather requires experience and expertise for making it indeed very useful. Here we present application notes that expand the usefulness of antibody phage display as a very versatile and robust antibody discovery tool.
