Beta2-glycoprotein I ( 2GPI) detection is important for the accurate diagnosis of autoimmune and chronic inflammatory disease. This book describes the main steps towards a successful obtaining, initial characterization, analytical applications and lab-scale production of a set of anti- 2GPI monoclonal antibodies.
