[The use of anti-A, anti-B and anti-AB monoclonal antibodies in a blood transfusion center. Preliminary results].

The properties of the anti-A, anti-B and anti-AB monoclonal antibodies were investigated by comparing these with 3 polyclonal antibodies with particular emphasis on specificity, titre and take-up. The results obtained suggest that monoclonal antibodies are highly specific and possess a similar titre but a superior take-up capacity to the polyclonal antibodies. It is concluded that they will be extremely valuable in immunohaematology laboratories.
