Immunofluorescence Validation of SARS-CoV-2 (COVID-19) Spike (cleavage site) in 293 Transfected Cells. Immunofluorescent analysis of 4% paraformaldehyde-fixed 293 spike transfected cells labeling SARS-CoV-2 (COVID-19) Spike (cleavage site) with orb1238707 at 20 mg/mL, followed by goat anti-rabbit IgG secondary antibody at 1/500 dilution (green) and DAPI staining (blue).

Overexpression Validation in Spike Transfected 293 Cells. Loading: 15 µg per lane of 293 cell lysate. Antibodies: SARS-CoV-2 (COVID-19) Spike (cleavage site), orb1238707 (4 µg/mL), 1 h incubation at RT in 5% NFDM/TBST. Secondary: Goat anti-rabbit IgG HRP conjugate at 1:10000 dilution. Lane 1: WT 293 cells and Lane 2: SARS-CoV-2 Spike overexpressed 293 cells.

ELISA Validation with SARS-CoV-2 (COVID-19) Spike Recombinant Protein. Antibodies: SARS-CoV-2 (COVID-19) Spike antibody (cleavage site), orb1238707 (1 µg/mL). A direct ELISA was performed using SARS-CoV-2 (COVID-19) Spike S1 recombinant protein (orb1227612) as coating antigen and the anti-SARS-CoV-2 (COVID-19) Spike antibody (cleavage site) as the capture antibody. Secondary: Goat anti-rabbit IgG HRP conjugate at 1:20000 dilution. Detection range is from 8 ng/mL to 1000 ng/mL.

Western Blot Validation with SARS-CoV-2 (COVID-19) Spike Recombinant Protein. Loading: 50 ng per lane of SARS-CoV-2 (COVID-19) Spike S1 recombinant protein orb1227612. Antibodies: SARS-CoV-2 (COVID-19) Spike (cleavage site), orb1238707, 1 h incubation at RT in 5% NFDM/TBST. Secondary: Goat anti-rabbit IgG HRP conjugate at 1:10000 dilution. Lane 1: 2.5 µg/mL and Lane 2: 5 µg/mL.
