Cells were stained with the appropriate conjugated antibodies for 30 min at 4°C, washed in 0.5% bovine serum albumin/phosphate-buffered saline (PBS) 2 mmol/L EDTA solution, and analyzed using FACSCalibur (BD Biosciences). The following antibodies (anti-human) were utilized: PE CD31: Miltenyi Biotec #130-118-965; FITC CD34: Miltenyi Biotec #130-113-178; APC CD144: Miltenyi Biotec #130-126-010; APC CD73: Miltenyi Biotec #130-124-011; PE CD45 (clone HI30): BioLegend #304008; FITC CD3: Miltenyi Biotec #130-113-690; PE CD90: Miltenyi Biotec #130-117-388; BV421 CD56: BD Horizon #562751; AF647 CD158 (KIR): BD Pharmingen #567324; FITC Perforin: eBioscience #11-9994-42; KO CD45: Beckman Coulter #A96416; PE NKp46: BD Pharmingen #557991; PE-Cy7 CD159α (NKG2A): Beckman Coulter #B10246; PEDazzle CD16: BioLegend #302054; PerCP-Cy5 CD94: BioLegend #302054; FITC IFNγ: Sysmex #AE092283; PE TNFα: BD Pharmingen #554513; CF594 IL-8: BD Horizon #563531.

According to the manufacturer’s instructions, peripheral blood mononuclear cells (PBMCs) were isolated using Ficoll density gradients. PBMCs were stimulated with Leukocyte Activation Cocktail (BD Pharmingen, San Diego, CA) at 37 °C for 4 h prior to intracellular staining using the manufacturer’s staining protocol. PBMCs were stained for surface markers, fixed, permeabilized with IntraPreReagent (Beckman Coulter, Fullerton, CA), and then stained with antibodies for intracellular markers. Anti-human mAbs against APC-CD4, FITC-CD56, FITC-IFN-γ, PE-CF594-CD3, PE-IL-2, PE-TNF-α, and V450-CD8, with controls, were purchased from BD Biosciences (San Jose, CA, USA). Data were acquired on a Gallios instrument (Beckman Coulter, Brea, CA) and analyzed with FlowJo software (Ashland, OR).

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.
