We therefore sought to identify biomarkers for aGVHD using antibody microarrays (Schleicher and Schuell Serum Biomarker Chips, Whatman) that simultaneously assayed 120 plasma proteins. We measured these proteins in a set of 42 patient plasma samples following an allogeneic bone marrow transplant (BMT): 21 patients with a diagnosis of aGVHD grade II-IV (+GVHD) and 21 patients without aGVHD (–GVHD) at similar times after transplant. We excluded data from 2 hybridizations that had very bright dots and appeared as outliers in preliminary principal components analysis, so that we finally compared 20 +GVHD to 20 -GVHD samples.
