title: An in-vitro assessment of the functional activity of monoclonal anti-D.
abstract: The response of human monocytes to red cells sensitized with known levels of monoclonal antibody to the Rh antigen D (anti-D) was compared with that of polyclonal anti-D. Monocyte response was determined by measuring red cell adherence, erythrophagocytosis, monocyte-mediated red cell lysis and luminol-dependent chemiluminescence. By all criteria, monoclonal and polyclonal antibodies showed comparable activity, with IgG3 antibodies promoting a greater monocyte-red cell interaction than IgG1 antibodies. It is suggested that monoclonal anti-D may be effective in the prophylaxis of haemolytic disease of the newborn, providing such material is clinically acceptable.
