Antibodies have evolved over millions of years to become a critical component of immunity, but in a few short decades we have dramatically expanded their potential for solving other problems. Our general understanding of an antibody is a unique immunoglobulin, shaped by the immune system in response to whatever infection we may have contracted. Dr. Katie Roberts and Amanda Turner at Bio-Rad Laboratories show how recombinant antibody technologies allow us to consider antibodies as precise, replicable, manufactured components that can facilitate biological research and cure diseases.
