Development of anti-human B blood group monoclonal antibodies suitable as a blood typing reagent

An improved procedure for the generation of high-avidity anti-human B blood group monoclonal antibodies (MAbs) was developed. One of them, termed 7A1-2, showed excellent qualities of titer, avidity, and intensity required for use as human B blood typing reagent. Hemagglutination inhibition studies with monosaccharides and oligosaccharides were carried out to determine the specificity of the MAb 7A1-2. These studies indicate that the antibody reacts with the immunodominant region of the antigen which is known to confer the serologic specificity of this blood group.

Monoclonal antibodies and the haemostasis laboratory: current position

In recent years research laboratories have produced a wide variety of monoclonal antibodies to haemostatic proteins. While these have proven very useful in fundamental research they have not, as yet, been widely used as routine reagents. This article reviews the range of monoclonal antibodies currently available and discusses their potential applications in routine laboratory practice.
