A monoclonal antibody (mAb, more rarely called moAb) is an antibody produced from a cell lineage made by cloning a unique white blood cell. All subsequent antibodies derived this way trace back to a unique parent cell.
Another strategy is so called passive immunotherapy. In this case the antibodies is produced externally in cultured cells and are delivered to the patient in the form of a drug. In mice expressing APP, both active and passive immunization of anti-Aβ antibodies has been shown to be effective in clearing plaques, and can improve cognitive function.
The culture supernatant can yield 1 to 60 μg/ml of monoclonal antibody, which is maintained at -20 °C or lower until required. [2] By using culture supernatant or a purified immunoglobulin preparation, further analysis of a potential monoclonal antibody producing hybridoma can be made in terms of reactivity, specificity, and cross-reactivity.

A bispecific monoclonal antibody (BsMAb, BsAb) is an artificial protein that can simultaneously bind to two different types of antigen or two different epitopes on the same antigen. [1] Naturally occurring antibodies typically only target one antigen. BsAbs can be manufactured in several structural formats.
Synthetic antibodies include recombinant antibodies, nucleic acid aptamers and non-immunoglobulin protein scaffolds. As a consequence of their in vitro manufacturing method the antigen recognition site of synthetic antibodies can be engineered to any desired target and may extend beyond the typical immune repertoire offered by natural ...
Afucosylated antibodies are intensely used in the field of advanced medicine, also due to their high ADCC (antibody-dependent cellular cytotoxicity). This makes them effective in binding to specific targets while minimizing damage to surrounding tissue. Some of the fields in which afucosylated antibodies are used or considered for application are:
