GeneTex monoclonal reagent s2 subunit spike protein, clone 1a9
A Duodenal crypt with small acinus, and with intracytosolic and intranuclear inclusions with halo and apoptosis consistent with a viral infection (H&E 20 × magnification). B Positive immunohistochemical expression of the SARS-CoV-2 spike protein in these duodenal crypts (arrows, 20× magnification, COVID-19-S2-Subunit of the spike protein, clone <t>1A9).</t> C Immunohistochemistry showing that ACE2 is expressed in enterocytes with strong expression on the cell surface. In situ hybridization of antisense s-SARS-CoV-2 ( D ) and sense s-SARS-CoV-2 ( E ) confirms viral tropism and replication in duodenal biopsies. Viral RNA is visualized as red dots in the cytoplasm and nucleus of enterocytes. Blue staining represents nuclear DNA counterstaining of enterocytes with DAPI
