Data Figures

Figure 1. Data for Unconjugated
(A) Flow cytometry analysis of dendritic cells derived from human peripheral blood mononuclear cells (PBMCs). Cells were processed with the EasySep™ Human CD14 Positive Selection Kit (Catalog #18058) and labeled with Mouse IgG1, kappa Isotype Control Antibody, Clone MOPC-21, followed by a rat anti-mouse IgG1 antibody, PE (solid line histogram). Filled histogram shows labeling with a mouse IgG1, kappa positive control antibody (Anti-Human CD83 Antibody, Clone HB15e, Catalog #60107) followed by a rat anti-mouse IgG1 antibody, PE.(B) Human embryonic stem (ES) cells were cultured using mTeSR™1 (Catalog #05850) on Corning® Matrigel®-coated glass slides, then fixed and labeled with Mouse IgG1, kappa Isotype Control Antibody, Clone MOPC-21, followed by goat anti-mouse IgG, FITC (inset) or with a positive control antibody of the same isotype, Anti-Human SSEA-5 Antibody, Clone 8e11 (Catalog #60063), followed by goat anti-mouse IgG, FITC (green).

Figure 2. Data for Alexa Fluor® 488-Conjugated
(A) Flow cytometry analysis of dendritic cells derived from human peripheral blood mononuclear cells (PBMCs). Cells were processed with the EasySep™ Human CD14 Positive Selection Kit (Catalog #18058) and labeled with Mouse IgG1, kappa Isotype Control Antibody, Clone MOPC-21, Alexa Fluor® 488 (solid line histogram). Filled histogram shows labeling with a mouse IgG1, kappa positive control antibody (Anti-Human CD83 Antibody, Clone HB15e, Alexa Fluor® 488, Catalog #60107AD). (B) Human induced pluripotent stem (iPS) cells were cultured using mTeSR™1 (Catalog #05850) on Corning® Matrigel®-coated glass slides, then fixed and labeled with Mouse IgG1, kappa Isotype Control Antibody, Clone MOPC-21, Alexa Fluor® 488 (inset) or with a positive control antibody of the same isotype, Anti-Human SSEA-5 Antibody, Clone 8e11, Alexa Fluor® 488 (Catalog #60063AD, green).

Figure 3. Data for APC-Conjugated
Flow cytometry analysis of dendritic cells derived from human peripheral blood mononuclear cells (PBMCs). Cells were processed with the EasySep™ Human CD14 Positive Selection Kit (Catalog #18058) and labeled with Mouse IgG1, kappa Isotype Control Antibody, Clone MOPC-21, APC (solid line histogram). Filled histogram shows labeling with a mouse IgG1, kappa positive control antibody (Anti-Human CD83 Antibody, Clone HB15e, APC, Catalog #60107AZ).

Figure 4. Data for Biotin-Conjugated
Flow cytometry analysis of dendritic cells derived from human peripheral blood mononuclear cells (PBMCs). Cells were processed with the EasySep™ Human CD14 Positive Selection Kit (Catalog #18058) and labeled with Mouse IgG1, kappa Isotype Control Antibody, Clone MOPC-21, Biotin followed by streptavidin (SAV) APC (solid line histogram). Filled histogram shows labeling with a mouse IgG1, kappa positive control antibody (Anti-Human CD83 Antibody, Clone HB15e, Biotin, Catalog #60107BT) followed by SAV APC.

Flow cytometry analysis of dendritic cells derived from human peripheral blood mononuclear cells (PBMCs). Cells were processed with the EasySep™ Human CD14 Positive Selection Kit (Catalog #18058) and labeled with Mouse IgG1, kappa Isotype Control Antibody, Clone MOPC-21, FITC (solid line histogram). Filled histogram shows labeling with a mouse IgG1, kappa positive control antibody (Anti-Human CD83 Antibody, Clone HB15e, FITC, Catalog #60107FI).

Figure 6. Data for PE-Conjugated
(A) Flow cytometry analysis of dendritic cells derived from human peripheral blood mononuclear cells (PBMCs). Cells were processed with the EasySep™ Human CD14 Positive Selection Kit (Catalog #18058) and labeled with Mouse IgG1, kappa Isotype Control Antibody, Clone MOPC-21, PE (solid line histogram). Filled histogram shows labeling with a mouse IgG1, kappa positive control antibody (Anti-Human CD83 Antibody, Clone HB15e, PE, Catalog #60107PE).
