Antibody refers to a class of protective immunoglobulin produced due to the stimulation of antigens such as pathogenic bacteria and viruses and can bind specifically to antigens. The two main types of antibody are polyclonal antibody and monoclonal antibody. The former one is usually produced by different B cell clones in the body and can recognize many different epitopes of a single antigen, while the later one is generated by identical B cells and only recognize the same epitope of an antigen thus have monovalent affinity. antibody drug discovery https://dataverify.creative-biolabs.com/antibody-drugs.htm
