Cells were harvested after stimulation and viability of cells post activation was measured using the LIVE/DEAD™ Fixable Aqua Dead Cell Stain Kit (Thermo Fisher Scientific). Surface staining of antigen was performed at 4°C for 20 minutes. For intracellular antigens, cells were fixed and permeabilized using the FOXP3/Transcription factor staining kit (eBioscience), and incubated with the appropriate antibody for 1 hour at 4°C. Acquisition of cells was performed using the BD FACSCantoTM II Flow Cytometer and subsequent analysis was performed using FlowJo (v9 or v10). The clone and dilution of antibodies used for flow cytometry were as follows: CD4-Pacific Blue (Biolegend, OKT4, 1:200), CD69-APC (Biolegend, FN50, 1:200), CD45RA-APC (Biolegend, HI100, 1:200), CD45RO-FITC (Biolegend, UCHL1, 1:200), DEFA1 (R&D Systems, 2μg/ml), anti-sheep IgG-NL557 (R&D Systems, 1:500). IFNγ expression was analyzed using the IFN-γ Secretion Assay (PE, Miltenyi Biotec) following manufacturer’s instructions.

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.
