Abstract

The present invention relates to methods for efficiently generating recombinant monoclonal antibodies derived from B cells of a non-human host which has been immunochallenged with one or more target antigens. The methods comprise the steps of identifying and isolating B cell that bind to the antigen by FACS, and recombining and enriching for thousands of cells to create a B cell library. Related products and methods, such as methods of producing expression libraries, are also disclosed.
