Human monoclonal antibodies are identified with the suffix "-umab". They originate from a human. [7] An example of a human monoclonal antibody is ustekinumab, which treats psoriasis. [6] During the early stages of the COVID-19 pandemic, reliable treatment options had not yet been found or approved. In reaction, convalescent blood plasma was ...
Antibodies are one of the ways the human body fights infection from the coronavirus. Researchers believe testing for covid-19 antibodies in plasma can lead to possible treatments for the virus and ...
