Whole blood was stained for flow cytometry with multiple combinations of the following mAbs: CD3-FITC (SP34) ; CD20-PE (3G8); CD8-PerCP (SK1); CD4-APC (L200); CD25-FITC (2A3); HLA-DR-PerCP (l243); Ki-67-FITC (B56) (all from BD Biosciences) and FoxP3-APC (PCH101) (EBiosciences), as described (17 (link), 18 (link)). Data were acquired with a FACSCalibur flow cytometer (BD Immunocytometry Systems) and analyzed with CellQuest software (BD Biosciences). CD4+ and CD8+ T cell percentages were obtained by first gating on lymphocytes and then on CD3+ T cells. Immune activation, and proliferation markers were determined by gating on lymphocytes, then on CD3+ T cells, and finally on CD4+CD3+ or CD8+CD3+ T cells.

For staining, 2 × 106 cells were stained with Zombie Aqua Viability Dye (BioLegend) in PBS for 10 min on ice, then Fc receptors were blocked with anti-CD16/CD32 antibodies from BD Biosciences (2.4G2) for an additional 10 min. After centrifugation, the supernatant was removed and cell were stained with a surface antibody cocktail containing in FACS buffer (PBS, 2 mM EDTA, 2% FBS) and Brilliant Stain Buffer Plus from BD Biosciences for 20 min on ice. The following antibodies were purchased from BioLegend; F4/80-PerCP/Cy5.5 (BM8), CD11c-PE/Cy7 (N418), CCR7-PE (4B12), CD90.2-A700 (30-H12), CD19-A700 (6D5), MHC-II-BV421 (M5/114.14.2), CD11b-BV605 (M1/70), CD8α-BV650 (53-6.7), Ly-6C-BV711 (HK1.4) and IL-12 PE (C15.6). CD40-FITC (HM40-3), CD103-APC (2E9), CD24-APC e780 (M1/69) and Granzyme B eFluor450 (NGZB) were obtained from Thermo Fisher Scientific. CD80-PE CF594 (16-10A1), CD45-BV786 (30-F11) and Ki-67 FITC (B56) were purchased from BD Biosciences. All samples were resuspended in FACS buffer and acquired on a BD Fortessa flow cytometer. Data were analyzed using FlowJo software from Tree Star, v10.5.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
