Research Abstract

Monoclonal antibodies have recently proven to be research reagents and biopharmaceuticals. Thus, it has become increasingly important to develop technologies to obtain a desired antibody. In this study, I aim to establish a novel system for generating chicken monoclonal antibody. To end this, I establish a novel fusion partner cell line from chicken B cell line DT40 by targeted disruption of immunoglobulin and thymidine kinase genes.
