CD4+ and CD8+ T cell responses to peptides covering SARS-CoV-2 Spike in response to mRNA vaccination in persons recovered from SARS-CoV-2 infection
<p>These files contain intracellular cytokine staining flow cytometry data for CD4+ and CD8+ T cells after exposure of serial PBMC to SARS-CoV-2 spike peptides or control antigens. PBMC are from subjects recovered from SARS-CoV-2 infection that subsequently received mRNA vaccination. The data were analyzed and exported from FlowJo version 10 as individual gated events and related Boolean subsets for four functional markers: CD40L, IFN-g, IL-2, and TNF-a. Counts and frequencies are both included.</p> <p> </p> <p><strong>Procedure for obtaining data:</strong></p> <p>Cryopreserved peripheral blood mononuclear cells (PBMC) were thawed and rested overnight. PBMC (1 x 10<sup>6</sup> per well) were stimulated with a SARS-CoV-2 spike overlapping peptide pool (JPT, 1 μg/mL each peptide; 0.4% final DMSO concentration), 0.4% DMSO as a negative control, or PHA-P (Remel; 1.6 μg/mL final concentration) as a positive control, in the presence of anti-CD28 and anti-CD49d (BD Biosciences) antibodies at 37°C for 6 hours. Brefeldin A (Sigma) was added after 2 hours. Cells were stained with Live/Dead Near IR dye (Invitrogen), treated with FACS lyse (BD Biosciences) and frozen at -80<sup>o</sup>C. For staining, the cells were thawed, washed, and permeabilized with Permeabilizing solution 2 (BD Biosciences) then stained with fluorochrome labeled monoclonal antibodies to anti-human CD3 mAb (clone UCHT) conjugated with PE-Texas Red (ECD; Beckman Coulter), anti-human CD4 mAb (clone SK3) conjugated with BV510 (Biolegend), anti-human CD8 mAb (clone SK1) conjugated with PerCP-Cy5.5 (BD Biosciences), and the activation markers anti-human CD40L mAb (clone TRAP1) conjugated with BV421 (BD Biosciences), anti-human IFNγ mAb (clone 4S.B3) conjugated with PE (BD Biosciences), anti-human IL2 mAb (clone MQ1-17H12) conjugated with APC (BD Biosciences), and anti-human TNFα mAb (clone MAb11) conjugated with FITC (BD Biosciences). Events were recorded with BD Fortessa and analyzed with FlowJo (v10 for Mac; BD). </p>

Assessment of the Humoral Immune Response to the SARS-CoV-2 Spike Protein Receptor Binding Motif
<p><strong>Figure S1.</strong> Purification of human antibodies against the RBM region of the SARS-CoV-2 spike protein using a recombinant RBM Sepharose 4B affinity column (3 x 1 cm, inner diameter) (A) and SDS-PAGE (10%) analysis of the eluate (1) alongside a standard low molecular weight marker (Sigma Chemical Co, Saint Louis, Mo, U.S.A.) stained with Coomassie Blue. <strong>Table S1</strong>: Microscale thermophoresis (MST) traces of anti-RBM antibodies binding to different concentrations of S1WT (red) and S2WT (green) peptides by MST. Relative fluorescence (RF) between the bound and unbound state was determined over a time of 21s with 20s MST-on time for evaluation. The blue bar indicates the ΔRF before the temperature gradient was applied, whereas the red bar shows the ΔRF during the thermophoresis. For interaction experi ments, the amount of NT.647-labeled antibodies was kept constant, while the concentration of unlabeled peptides varied from 0.5 µg/mL–0.12 ng/mL. The assay was performed in PBS containing 0.05% Tween 20 and after a short incubation period, the samples were analyzed in standard glass MST NT.115 capillaries. <strong>Table S2:</strong> One-dose regime AstraZeneca-Oxford vaccinated serum information. <strong>Table S3</strong>: Heterologous booster dose vaccinated serum information.</p>
