Towards a better definition of human leucocyte surface molecules

At the 4th International Workshop on Human Leucocyte Differentiation Antigens workers from 525 laboratories jointly evaluated and/or submitted about 1100 different monoclonal antibodies to human leucocyte surface molecules. At the final conference of the workshop agreement was reached on 35 new cluster determinants (CDs) and subclusters. In addition, seven previously established clusters were redefined. This report provides basic information concerning the molecules defined by these antibodies and some highlights of the conference.
