FIGURE 2.
Longitudinal serum SARS-CoV-2 antibody titers in pediatric patients receiving convalescent plasma (CP) transfusion therapy. Antibody titers expressed as reciprocal serum dilution against SARS-CoV-2 antigens in four pediatric patients (CD4, CD15, CD17, and CD25), and corresponding CP donors (open symbols) before and after plasma transfusion. Antibody titers against (A-D) the SARS-CoV-2 receptor-binding domain of the spike (S) protein, (E-H) the full-length SARS-CoV-2 S protein (FL), and (I-L) the nucleoprotein of SARS-CoV-2 (N). Dashed lines denote the lower limit of detection (LLOD) of the assay (1:50 serum dilution)
