Fig 3. Analyses using western blotting and SDS-PAGE under reducing conditions.
Left side is a representative western blot showing IgY from adjuvant-only immunized eggs (Lane A) and from eggs that were immunized with SARS-CoV-2 RBD. The anti-RBD IgY antibody specifically binds to the RBD protein (Lane B). Right side shows the SDS-PAGE of recombinant RBD (Lane C) (molecular weight 26 kDa).
