title: [Technique for automating HLA-DR typing].
abstract: Two types of anti-class II coated magnetic beads were compared for the use in isolation of B lymphocytes from whole blood. The HLA DR typing was performed in parallel after separation of the cells by the rosette technique. The depletion was monitored by Flow cytometry using CD2 and CD20 antibodies. Typing was performed using classic lymphocytotoxicity test of Propidium-Iodide-Carboxyfluorescein diacetate fluorescence. The results were scored with an ordinary microscope or by photometric evaluation. These techniques lead to simplification in cell isolation from small amounts of blood with an important gain of time and a less subjective interpretation of DR phenotyping was until now long and difficult.
