![]() Furthermore, this process allows to fine-tune the affinity of the monoclonal antibody and the production of highly stable cell lines. During a pandemic, there is no time to waste in the development and clinical testing of therapeutic modalities, including vaccines, nucleic acids, small molecules, convalescent serum, intravenous. This makes them easier to identify and deal with. The advantages of producing mAbs through recombinant processes is the possibility to use expression vectors with higher production yields than mouse ascites or hybridoma culture supernatant (in the g/l range). Once bound, the antigens - and the substances they are found on - are merged tightly together. Scientists discovered that we could make antibodies to bind to antigens on other substances, and not just those on pathogens. ![]() This means that only one type of antibody will bind to a matching antigen. This process is called biopanning and is usually repeated several times to identify antibody-bound phages that consistently bind antigens with high affinity. When a pathogen infects the body, the lymphocytes recognise these antigens as foreign and attack them by producing antibodies.Īntibodies bind to specific antigens on pathogens. Pathogens have proteins on their surface called antigens. Antibodies are large Y-shaped proteins called immunoglobulins which are produced by B cells as part of the adaptive immune response when encountering a foreign. Monoclonal antibodies are identical copies of one type of antibody.Īntibodies are proteins produced by a type of white blood called lymphocytes. 'Mono' means 'one' and 'clone' means 'identical copy'. ![]() Greg Foot describes how monoclonal antibodies are produced and how they work ![]()
