On 16 April 2021, the FDA revoked the emergency use authorization (EUA) that allowed for the investigational monoclonal antibody therapy bamlanivimab, when administered alone, to be used for the treatment of mild-to-moderate COVID-19 in adults and certain pediatric patients. [13] The EUA was issued to Eli Lilly and Co. [3]
This list of over 500 monoclonal antibodies includes approved and investigational drugs as well as drugs that have been withdrawn from market; consequently, the column Use does not necessarily indicate clinical usage. See the list of FDA-approved therapeutic monoclonal antibodies in the monoclonal antibody therapy page.
Antibodies are glycoproteins that are naturally produced by the immune system. Each antibody contains four polypeptides of Y shapes and has unique recognition sites of the targets, such as cell surface antigen, and transmembrane proteins on cancer cells and infectious organisms (viruses and bacteria). Upon binding to the antigen, antibodies ...
Antibody-directed enzyme prodrug therapy (ADEPT) involves the application of cancer-associated monoclonal antibodies that are linked to a drug-activating enzyme. Systemic administration of a non-toxic agent results in the antibody's conversion to a toxic drug, resulting in a cytotoxic effect that can be targeted at malignant cells.
A pentamer is an entity composed of five subunits. In chemistry, it applies to molecules made of five monomers . In biochemistry, it applies to macromolecules, particularly pentameric proteins , made of five protein sub-units.

As a flow-cytometry-based application, tetramers are also easy to use and have a short assay time, similar to Antibody-based flow cytometry studies. [4] MHC tetramers are used in studies of pathogen immunity and vaccine development, in evaluation of antitumor responses, in allergy monitoring and desensitization studies, and in autoimmunity.
IgM is the first immunoglobulin expressed in the human fetus (around 20 weeks) [46] and phylogenetically the earliest antibody to develop. [47] IgM antibodies appear early in the course of an infection and usually reappear, to a lesser extent, after further exposure. IgM antibodies do not pass across the human placenta (only isotype IgG). [48]
