Figure 7. Depletion assay with P136-155 and P151-170 of SARS-CoV-2 NP protein. (A) Reactivity of NP-specific antibodies from 10 patients to P136-155 and P151-170 peptide was assessed in P136-155 and P151-170 adsorbed and non-adsorbed sera against reduced and non-reduced forms of NP by ELISA. (B) Two representative serum samples were also tested by Western blot. The solid lines represent mean values ± SD, P<0.05 (*). NP: Nucleocapsid.
