Monoclonal Antibody News and Research

RSS

Monoclonal antibodies (MAbs) are produced from a single B cell clone and can bind to a single type of antigen binding site. MAbs are homogenous antibodies that cannot form lattices with monomeric proteins as they can bind to only a single epitope on the antigen. Developed in the 1970s, MAbs can be produced against any given substance. Thus they can be used to detect and purify any substance of interest. This has made MAbs a powerful tool of molecular biology, biochemistry, and medicine.
