False colour image of Western blot: Anti-SARS-CoV-2 Spike Glycoprotein S1 antibody [8B12-C2] - BSA and Azide free staining at 1/500 dilution, shown in green; Mouse anti-6X His Tag® [HIS.H8] (ab18184) loading control staining at 1/1000 dilution, shown in red. In Western blot, ab282749 was shown to bind specifically to SARS-CoV-2 Spike Glycoprotein S1. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3 % milk in TBS-0.1 % Tween® 20 (TBS-T) before incubation with primary antibodies overnight at 4 °C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Donkey anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed (ab216778) and Donkey anti-Goat IgG H&L (IRDye® 800CW) preabsorbed (ab216775) at 1/20000 dilution.

Western blot - Recombinant Anti-SARS-CoV-2 Spike Glycoprotein S1 antibody [8B12-C2] (ab282749) Whole cell lysates of HEK293T cells expressing Sars-CoV2 Spike-P2A-GFP protein either as the wild-type (Wt) or the B 1.351 variant version were separated by 7.5% SDS-PAGE and transferred to nitrocellulose membrane. Membranes were blocked in 3% NFDM in PBS-T (0.05% Tween) for 1h at RT and incubated with anti-P2A (3H4-3A5, 1:500) or ab282749 (0,1µg/ml) diluted in 0.5% NFDM/PBS-T o/n at 4°C. After washing and incubation with HRP-coupled secondary antibody for 1h at RT, signals were visualized by ECL reaction and Chemidoc or X-ray film detection.
