Human whole blood (1 mL) from SARS-CoV-2–reactive donors were incubated for 8 hours with Brefeldin A. Simultaneously, cells were either left unstimulated (A) or incubated with a selection of SARS-CoV-2 PepTivators Prot_N (130-126-700) (B) or Prot_S1 (130-127-041) (C). Blood samples were lysed and then fixed and permeabilized afterwards. Subsequently, cells were stained with the flow panel included in this kit. Cells were analyzed using a MACSQuant ® Analyzer 16. Doublets, debris, and dead cells as well as CD14 + and CD20 + cells were excluded. After pregating on CD3 as well as CD4 and CD8, respectively, activation marker and cytokine expression were assessed, e.g. CD154 and IL-2 for CD4 + T cells and TNF-α and IFN-γ for CD8 + T cells. |
