Generation of Discriminative Human Monoclonal Antibodies from Rare Antigen-specific B Cells Circulating in Blood

Overview

This article describes a method for producing fully human monoclonal antibodies from circulating B lymphocytes in human blood. The technique enables the generation of antibodies that can effectively discriminate between closely related antigens, which is crucial for applications like immunotherapy.
