Additional file 1: of CD33/CD3-bispecific T-cell engaging (BiTE®) antibody construct targets monocytic AML myeloid-derived suppressor cells

Table S1. Fluorochrome-coupled antibodies and/or chemical dyes for flow cytometry. Table S2. AML-derived PBMCs (n=12) were treated with AMG 330 for three days. The median fluorescence intensity (MFI) of granzyme B (Grz B), CD107, perforin, CD69, CD137, CD25, CD154, IL2, IFNγ, and the cells’ expansion index was assessed by FACS in CD4+/CD8+ CD3+ T-cells as indicated. The association between those variables and the PBMCs’ initial frequency of HLA-DRlo cells among CD14+ cells was calculated using a Pearson correlation analysis. Abbreviations: p, p-value; r, Pearson correlation. Table S3. AML-derived PBMCs (n=12) were treated with AMG 330 for three days.
