The pooled PBMCs and lymph node cells from the healthy donors and the lung cancer patients were stained for flow cytometry. The following panel of mouse anti-human mAbs, all purchased from BD Biosciences (San Jose, CA, USA) or eBioscience (San Diego, CA, USA), was used: anti-human CD3-APC.cy7 (BD, 557832, SK7), anti-human CD4-Percp.cy5.5 (BD, 560650, RPA-T4), anti-human CD45RA-FITC (eBioscience, 11-0458-42, HI100), and anti-human CCR7-PE.cy7 (BD, 557648, 150503). The cell data were acquired using a 10-laser Gallios (Beckman Coulter Inc., Brea, CA, USA) analytical flow cytometer. Unstained and single fluorochrome-stained cells were used as controls to provide accurate compensation and data analysis. The results were analyzed with Kaluza software.

Phenotyping Extracellular Vesicles by Flow Cytometry

Check if the same lab product or an alternative is used in the 5 most similar protocols
Our specimen preparation protocol was modified from the methods suggested by Headland et al. (13 (link)). The cellular origin of plasma derived EVs were identified by the following CD markers; CD235 for erythrocytes, CD41A for platelets, CD146 for endothelial cells, CD66b for neutrophils, CD14 for monocytes, CD19 for B lymphocytes, and CD3 for T lymphocytes. Five microliters of the isolated EVs samples were diluted with PBS to a total volume of 50 μL. The samples were incubated with an antibody cocktail, comprised of anti-human CD9-FITC (ImmunoTools, Friesoythe, Germany), anti-human CD235-PE (BD Pharmingen, NJ, US), anti-human CD41A-PE-Cy5 (BD Pharmingen, NJ, US), anti-human CD146-PE-Cy7 (BD Pharmingen, NJ, US), anti-human CD66b-PE (BD Pharmingen, NJ, US), anti-human CD14-PECF594 (BD Pharmingen, NJ, US), anti-human CD19-PERCP-Cy5.5 (BD Pharmingen, NJ, US), and anti-human CD3-APC-Cy7(BD Pharmingen, NJ, US), for 1 h in the dark at room temperature. Flow cytometry data acquisition was done immediately after the antibody incubation process.

T lymphocytes from the patients with CP were stained for flow cytometry. The following panel of mouse anti-human monoclonal antibodies (mAbs) used were all purchased from BD Biosciences (Franklin Lakes, NJ, USA) or eBioscience (San Diego, CA, USA): anti-human CD3-APC.Cy7 (cat. 557832, SK7; BD Biosciences), anti-human CD4-Percp.Cy5.5 (cat. 560650, RPA-T4; BD Biosciences), anti-human CD8-Alexa Fluor 700 (cat. 56-0088-42, RPA-T8; eBioscience), anti-human CCR7-PE.eFluor610 (cat. 61-1979-42, 3D12; eBioscience), anti-human CD62L-APC (cat. 17-0629-42, DREG56; eBioscience), anti-human CD45RO-FITC (11-0457-42, UCHL1; eBioscience), anti-human CD95-PE.Cy7 (cat. 561633, DX2; BD Biosciences), anti-human CD103-APC (cat. 17-1037-41, Ber-ACT8; eBioscience), and anti-human CD122-PE (cat. 554525; BD Biosciences). Cellular data were obtained from a BD LSRFortessa analytical flow cytometer. Unstained and single fluorochrome-stained cells served as controls for accurate compensation and data analysis. Cells in each sample were counted, and the data were analyzed with FlowJo version 10 (FlowJo, Ashland, OR, USA).

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.
