Surface Staining of Immune Cells

For surface staining of human specimens, cell suspensions were incubated with the appropriate combination of the following monoclonal antibodies: CD19-PC5 (J3-119, Beckman Coulter), CD80-Brilliant Violet 421™ (2D10, BioLegend®), CD83-APC (HB15e, BioLegend®), CD86-APC (IT2.2, BioLegend®), and HLA-DR-V500 (G46-6, BD Horizon™). For surface staining of mouse specimens, cell suspensions were incubated with Fc-blocking antibody (Bioxcell, 2.4G2) to avoid unspecific Fc-Receptor binding. After washing, the cells were incubated with the appropriate combination of the following ­antibodies: CD11b-PECy7 (M1/70, BioLegend®), Ly6G-PE (1A8, BD Biosciences), Ly6C-Biotin (AL-21, BD Biosciences), CD3-APC(17A2, BioLegend®), CD45R-B220-PerCP-Cy5.5 (RA3-6B2, eBiosciences). To detect anti-Ly6C-Biotin antibody binding, cells were subsequently stained with streptavidin-FITC (Dako). The samples were acquired with BD LSRFortessa (BD Biosciences), and results were analyzed with FlowJo software (Tree Star, Inc.).

Ultrapure lipopolysacharide (LPS, TLR4 ligand, 100ng/mL used in whole blood assays) isolated from Salmonella minnesota, was obtained from InvivoGen. PAM3 (Pam3CSKKKK, N-palmitoyl-S-[2,3-bis- (palmitoyloxy)-propyl]-(R)-cysteinyl-(lysyl)3-lysine, TLR2/1 ligand, 300ng/mL used in whole blood assays, 10 µg/mL used in PBMC phosphoflow assays) was obtained from EMC Microcollections. Log-phase derived live BCG expressing green fluorescent protein (BCG-GFP, Pasteur strain; used at 3.5 × 105 CFU/mL in assays) was donated by Muazzam Jacobs, University of Cape Town.
The following antibodies were used for whole blood flow cytometry: CD14-QDot605 (clone Tuk4, Invitrogen), TNF-α-PECy7 (Mab11), CD11c-V450 (B-ly6), CD86 (B70/B7–2)-PE (both from BD Pharmingen), CD11c-PerCPCy5.5 (Bu15), HLA-DR-AlexaFluor700 (L243), IL-12/23p40-Pacific Blue (C11.5), IL-10-PE (JES3-19F1), IL-6-APC (MQ2-13A5), CD40-PerCP-Cy5.5 (5C3) and CD83-APC (HB15e) (all from Biolegend). CD66a/c/e (ASL-32, Biolegend) was conjugated in-house to QDot565 (Invitrogen) using the manufacturer’s protocol. The following antibodies were used for PBMC phosphoflow experiments: CD14-Pacific Blue (clone M5E2), p-p38 MAPK-PECy7 (36/p38: pT180/pY182), p-Erk1/2-AlexaFluor647 (20A: pT202/pY204), IκBα-PE (25/IκBα/MAD-3), all from BD Biosciences.

Multiparameter Immunophenotyping of T-Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
To determine CD86, CD83 and HLA-DR on DCs the cells were washed twice using FACS buffer and were subsequently stained using CD86-PE (IT2.2, BD Biosciences), CD83-APC (HB15e, Biolegend) and HLA-DR-PerCp (L243, BD Biosciences) for 30min at 4°C in FACS buffer. Cells were washed once more with FACS buffer and were analysed on a FACS Canto II apparatus. To assess the capacity of T-cells to produce cytokines/ chemokines, cells were permeabilized with PermWash (BD Pharmingen) according to manufacturer’s protocol to stain for intracellular markers. Cells were stained for p24-RD1 (Beckman Coulter, KC57-RD1) and IFN-γ-FitC (4S.B3), IL2-PerCp-Cy5.5 (MQ1-17H12), IL-4-APC (MP4-25D2), TNF-α-PE-CF594 (MAb11), Mip-1β-AlexaFluor700 (D21-1351) (all from BD Bioscience) for 30min at 4°C in PermWash. Next, these cells were washed once with PermWash, resuspended in FACS buffer (PBS+ 2%FCS) and measured on a FACS Canto II apparatus. The histograms depict all T-cells capable of producing a certain cytokine/ chemokine at the optimal time point. The optimal time point was determined by the percentage of live cells (>50%) and the level of HIV-1 infection, which varied per donor and per virus between day 5 and 7.

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.
