Buffy coats collected from 5 healthy CMV seropositive donors were obtained from Memorial Blood Bank (Minneapolis, MN). Peripheral blood mononuclear cells (PBMCs) were isolated by density gradient centrifugation using Ficoll-Paque (GE Healthcare) and cultured with K562 cells at a 2:1 (effector:target) ratio for 5 hours in RPMI media supplemented with 10% fetal bovine serum (Gibco). GolgiStop and GolgiPlug protein transport inhibitors (BD Biosciences) were added 1 hour into the assay. The following antibodies were used for functional analysis of NK cell subsets: BV785-conjugated anti-CD3 (clone OKT3; Biolegend), PECy7-conjugated anti-CD56 (BioLegend; 318318), PE-CF594-conjugated anti-CD57 (Biolegend; 359620), PE-conjugated NKG2C (R&D Systems; FAB138P-025), PerCP-Cy5.5-conjugated anti-CD107a (Biolegend; 328616), AF700-conjugated anti-TNF (Biolegend; 502928) and BV605-conjugated IFN-γ (Biolegend; 502536). The K562 cell line was purchased from ATCC (Manassas, Virginia) and is screened monthly for mycoplasma contamination. The experiment was performed at 2 independent times. Two-sided, paired t-tests in GraphPad were used to determine significance. Error bars represent SEM.

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.
