Cd89 pe a59

MDM, MDDC, or PBMC were stained using a multicolored flow cytometry panel designed to determine Fc receptor expression. Cells were stained with CD3 V450 (UCHT1), CD14 Qdot 605 (T[u]K4) (Invitrogen), CD16 Pacific Orange (3G8) (Invitrogen), CD11c A700 (B-ly6), CD123 phycoerythrin (PE)-Cy5 (9F5), CD32 allophycocyanin (APC) (FLI8.26), CD64 APC H7 (10.1), CD89 PE (A59), and CD19 fluorescein isothiocyanate (FITC) (HIB19). Unless otherwise specified, all antibodies were sourced from BD Biosciences. Dead cells were excluded from analysis through staining with Aqua viability dye (Invitrogen).

Red blood cell-lysed whole blood or cells isolated from mucosal tissues were stained using a combination of multicoloured flow cytometry panels designed to determine Fc-receptor expression on CD14+ monocytic cells, mDC or NK cells. Briefly, for overall cellular phenotyping; CD3 V450 [UCHT1], CD4 PECy7 [SK3] (Biolegend), CD8 Pacific Orange [3B5] (Invitrogen), CD19 BV650 [SJ25C1]. For CD14 and mDC FcR Phenotyping; CD3 V450 [UCHT1], CD14 Qdot 605 [TüK4] (Invitrogen), CD16 Pacific Orange [3G8] (Invitrogen), CD11c A700 [B-ly6], CD123 PECy5 [9F5], CD32 APC [FLI8.26], CD64 APC H7 [10.1], CD89 PE [A59], CD19 FITC [HIB19]. For NK cell FcR phenotyping; CD15 BV650 [W6D3] (Biolegend), CD16 PECy7 [3G8] (Biolegend), CD66b FITC [G10F5] (Biolegend), CD64 APC H7 [10.1], CD56 PECy5 [HCD56] (Biolegend), CD45 A700 [HI30] (Biolegend), CD89 PE [A59], CD3 V450 [UCHT1], CD32 APC [FLI8.26]. Unless otherwise specified, all antibodies were sourced from BD Biosciences. Anti-FcRs were able to detect antibody-occupied FcR as indicated by the manufacture and in house controls. Dead cells were excluded from analysis through staining with Aqua Viability Dye (Invitrogen).
