Initial statistical clustering: definition of temporary clusters of monoclonal antibodies for the duration of the workshop.

Statistical clustering was performed on flow cytometry data generated from the reactivities of 189 mAbs with 56 cell preparations or cell lines (targets). Six targets were excluded from the statistical clustering because of non-reproducibility of data from the internal controls. Thirty-six temporary clusters (TC) were formed which were subjected to further examination in the second phase of the workshop.
