title: A possible split of antigen DQw1 identified by antiserum T3516.
abstract: One of the human class II antigens DQw1, which was officially recognized at the 9th International Histocompatibility Workshop in 1984, has a comparatively broad spectrum. One multiparous woman's serum was confirmed to have an antibody which shows a reaction pattern of short DQw1 or a split of DQw1. Our analysis was performed with a population study, two-dimensional gel electrophoresis and blocking experiment by monoclonal antibodies.
