Concomitant detection of the SARS-CoV-2 surface Spike and intracellular nucleocapsid antigens in pAECs. pAECs (cell preparations from two different subjects) were either (A) mock-infected or (B) infected with authentic SARS-CoV-2 D614G or (C) infected with Alpha variant of concern. Cells were stained intracellularly with Alexa Fluor 488 pre-coupled anti-nucleocapsid (anti-N) Ab (clone mBG17) for the identification of infected cells. (A–C) Flow cytometry contour plots showing representative staining with the SARS-CoV-2 anti-S2 CV3-25 antibody.
