Immunohistochemistry Validation of SARS-CoV-2 (COVID-19) Envelope in COVID-19 Patient Lung. Immunohistochemical analysis of paraffin-embedded COVID-19 patient lung tissue using anti-SARS-CoV-2 (COVID-19) Envelope antibody (orb1238718, 0.5 µg/mL). Tissue was fixed with formaldehyde and blocked with 10% serum for 1 h at RT; antigen retrieval was by heat mediation with a citrate buffer (pH6). Samples were incubated with primary antibody overnight at 4 ˚C. A goat anti-rabbit IgG H&L (HRP) at 1/250 was used as secondary. Counter stained with Hematoxylin. Strong signal of SARS-COV-2 envelope protein was observed in macrophage of COVID-19 patient lung, but not in non-COVID-19 patient lung.

Western Blot Validation with SARS-CoV-2 Envelope Recombinant Protein. Loading: 50 ng per lane of SARS-CoV-2 Envelope recombinant protein (orb1228241). Antibodies: SARS-CoV-2 (COVID-19) Envelope, orb1238718, 1 h incubation at RT in 5% NFDM/TBST. Secondary: Goat anti-rabbit IgG HRP conjugate at 1:10000 dilution. Lane 1: 1 µg/mL and. Lane 2: 2 µg/mL.

ELISA Validation with SARS-CoV-2 Envelope Recombinant Protein. Antibodies: SARS-CoV-2 (COVID-19) Envelope Antibody, orb1238718. A direct ELISA was performed using SARS-CoV-2 Envelope recombinant protein (orb1228241) as coating antigen and the anti-SARS-CoV-2 (COVID-19) Envelope antibody as the capture antibody. Secondary: Goat anti-rabbit IgG HRP conjugate at 1:20000 dilution. Detection range is from 1 ng/mL to 3000 ng/mL.

ELISA Validation. Antibodies: SARS-CoV-2 (COVID-19) Envelope Antibody, orb1238718.
