monoclonal antibodies are made to target specific antigens. which of the following actions by monoclonal antibodies can be used on a target cell? (select all that apply) 1) make cell more visible to immune system 2) block growth signlas 3) block cytokine release 4) increse WBC count
1) make cell more visible to immune system 2) block growth signlas 3) block cytokine release *MABs are made to suppress a specific part of immune response or make cells more visible to immune system to stop tissue or cell damage*
