Hello..what is the monoclonal antibody?how it works?

There are many: Before hybridoma technology, if we wanted an antibody against something, we had to inject an animal and get a diverse mixture. Today, a single antibody with a specific sequence can be produced in unlimited quantities. It was one of the key breakthroughs in 20th century medicine & a many diagnostic & therapeutic agents resulted.

Monoclonal antibody: A monoclonal antibody means that it is a specific antibody made by a cell, and that all the antibodies are the same. Usually this is done to try to target a specific receptor on a cell or virus. For instance if a scientist finds a susceptible part of a virus and wants to target it, they will try to create an monoclonal antibody to bind to it. This process is done for a multitude of reasons.
