Anti bdca1

Freshly prepared PBMCs were used. Subpopulations of T cells, B cells, natural killer (NK) cells and antigen-presenting cells (APC) were characterized by surface staining with fluorescence labelled anti-CD3, anti-CD4, anti-CD5, anti-CD8, anti-CD14, anti-CD16, anti-CD19, anti-CD25, anti-CD27, anti-CD38, anti-CD45RA, anti-CD45RO, anti-CD56 and anti-HLA-DR (BD Bioscience); anti-BDCA1, anti-BDCA2, anti-BDCA3, anti-BDCA4 and anti-slan (Miltenyi Biotec). Negative controls included directly labeled or unlabeled isotype-matched irrelevant antibodies (BD Biosciences). Freshly prepared CSF cells were used directly for FACS analysis. Fluorescence-labeled antibodies for surface staining were used as follows: anti-CD3, anti-CD4, anti-CD8, anti-CD14, anti-CD16, anti-CD19, anti-CD25, anti-CD27, anti-CD45RA, anti-CD45RO, anti-CD56 and anti-HLA-DR (BD Bioscience); anti-BDCA1 and anti-slan (Miltenyi Biotec). All cells were measured on a LSR-Fortessa (BD Biosciences) and evaluated by FACS-Diva Software (BD Bioscience).
