Cd45ra apc cy7

MNC from FLT3-ITD AML BM samples were stained for lineage markers using biotinylated antibodies: CD4 (RPA-T4; Biolegend), CD8a (RPA-T8; Biolegend), CD19 (HIB19; Biolegend), CD41 (MEM-06; Sigma), CD235alpha (HIR2; eBioscience), CD56 (B159; BD Pharmingen). Cells were then stained with the following fluorochrome-conjugated antibodies: CD34-FITC (581; BD Pharmingen), CD90-PE (5e10; BD Pharmingen), CD33-PC5.5 (D3HL60, Beckmann Coulter), CD45RA-APC Cy7 (H1100; BD Pharmingen), Streptavidin-eFluor 450 (eBioscience), CD38-APC (HB7; BD Pharmingen), CD45-APC-Cy7 (2D1; BD Pharmingen). PI was added as live/dead marker. Cell sorting was performed on a FACS Aria II (Becton Dickinson, Heidelberg, Germany). Sorting purity of >98% was routinely obtained.

The following fluorochrome-conjugated Abs were used for polychromatic flow cytometry analysis: CD3-Pacific Blue (UCHT1), CD4-Alexa700 (RPA-T4), CD45RA-APC-Cy7 (HI100), CCR6-PE (11A9), CCR7-PE-Cy7 (3D12), CD25-PE (M-A251), CD26-FITC (L272), CD127-AF647 (HIL-7R-M21), CD161-PE-Cy5 (DX12), IFNγ-Alexa 700 (B27), CCR5-PE (2D7), CXCR4-PE (12G5), and CD8-APC H7 (SK1) (BD Pharmingen), CD45RA-APC eFluor780 (HI100), CD56-FITC (MEM188), IL-17A-PE (eBio64DEC17), FoxP3-AF488 (PCH101), TNFα-Pacific Blue (Mab11), and IL-17A-eFluor660 (eBio64CAP17) (eBioscience), CD8-FITC (BW135/80), CD19-FITC (LT19) (Miltenyi), CCR7-PE (150503) (R&D) and CD31-BV605 (WM59) (Biolegend). Cell phenotype was analyzed by flow cytometry using the BD LSRII cytometer and BD Diva software. A viability staining Vivid (Invitrogen) was included in each staining cocktail to exclude dead cells from our analysis. FACS analysis was performed using the FlowJo software (^©Tree Star, Inc.). For multicolor analysis, all Abs were titrated for an optimal noise/signal ratio and Abs cocktails were validated by comparing single to multiple staining. Positivity gates were placed based on fluorescence minus one (FMO), as previously described [21 (link),101 ].

Fluorochrome-conjugated Abs used for polychromatic flow cytometry analysis were CD3-Pacific Blue (UCHT1), CD4-Alexa700 (RPA-T4), CD45RA-APC-Cy7 (custom), CCR4-PE-Cy7 (1G1), CXCR3-PE-Cy5 (1C6), CCR6-PE (11A9), Ki67-FITC, IFN-γ-AlexaFluor 700 (B27) (BD Pharmingen), CD56-FITC (MEM188), IL-17-PE (64DEC17) (eBioscience), HIV-p24-FITC (FH190-1-1) (Beckman Coulter), CD8-FITC (BW135/80), and CD19-FITC (LT19) (Miltenyi). A viability dye (Molecular Probes^® LIVE/DEAD^® Fixable Dead Cell Stain Kits, Invitrogen) was used to exclude dead cells. Cells were stained and analyzed by FACS using the BD LSRII cytometer and the FlowJo software, as previously described [129 (link)].
