    This chapter discusses the strategies and procedures for the preparation of monoclonal antibodies (McAb). The derivation of permanent lines of hybrid cells, producing McAb, exhibiting certain desired properties, presents widely different degrees of difficulty. Desired properties include not only specific recognition of an antigen and other no less critical properties are the fine specificity of the antibody, avidity and kinetic parameters important for radioimmunoassays, cytotoxic properties necessary for direct complement-dependent lysis. The insoluble antigen and the antibody in the culture fluid are allowed to react. The free antibody is washed away. The amount of monoclonal antibody bound is measured directly or by binding of a second, labeled antibody capable of recognizing the first. Monoclonal antibodies can be easily labeled internally at high specific activity, using radioactive amino acid precursors. The choice of these is based on the efficiency of incorporation of labeled amino acids into secreted immunoglobulin in culture conditions. The hemagglutination assays are based on the ability of an antibody to agglutinate red cells, carrying the specific antigen. These assays have all the advantages in terms of extreme simplicity, speed, and direct visual reading of the results.
