For staining of peripheral blood mononuclear cells with purified antibodies, 100,000 cells were incubated with 0.2μg of antibody diluted in PBS/0.5% BSA/0.02% NaN3 (FACS medium) for 1h on ice as previously described [42 (link), 43 (link)]. Cells were centrifuged 400g/5min and supernatant was removed. The cells were incubated 30mins on ice with secondary antibodies, washed with FACS medium and analyzed with FACS calibur instrument (BD, Franklin Lakes, NJ, USA) and FlowJo or CellQuest software. The following antibodies were used: PE-anti-CD56 (DAKO, Glostrup, Denmark, clone MOC-1), FITC-anti CD3 (DAKO, clone UCHT1), APC-anti-NKG2D (eBioscience, San Diego, USA, clone CX5), APC-anti-NKp46 (eBioscience). Isotype control IgG1-FITC (DAKO), IgG1-PE (DAKO) and IgG1-APC (eBioscience) served as negative controls. NK cells were gated based on positive CD56 expression and lack of CD3 expression. At least 2,500 gated NK cells were analyzed in each reading.

All reagents and antibodies were diluted in a calcium chloride/PBS solution (CaCl2 2.5 mmol/L, pH 7.4, 0.2 μm filtered). The optimal antibody concentration was determined by titration. The following reagents and antibodies were used: Annexin V-Cy5-APC (Allophycocyanin, MBL international Corporation, detection of phosphatidylserine, 1:300), CD31-FITC (Fluorescein isothiocyanate, eBioscience, monoclonal mouse anti-human, 1:1000), CD41-PE (Phycoerythrin, Dako, monoclonal mouse anti-human, 1:200) and CD11b-PE (BD Biosciences, USA, monoclonal mouse anti-human, 1:100). Isotype controls used were IgG1-PE, IgG2a-PE and IgG1-FITC (all from DAKO). For the Annexin V-APC negative control, Annexin V-APC was diluted 1:300 in citrate/PBS solution. Endothelial MP were defined as CD31+ (CD41-), platelet as CD41+ (showing weak CD31+) and leukocyte MP as CD11b+.

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.
