SARS-Cov-2 Spike 26P Antibodies Detect Spike S1 Proteins of all Variants except Gamma Variant in an ELISA.Coating Antigen: SARS-CoV-2 spike S1 proteins WT, alpha variant (B.1.1.7), beta variant (B.1.351), gamma variant (P.1), delta variant (B.1.617.2), mu variant (B.1.621), and omicron variant (B.1.1.529), 1 μg/mL, incubated at 4°C overnight. Detection Antibodies: SARS-CoV-2 Spike 26P antibody, orb1238713, dilution: 200 and 1000 ng/mL, incubate at RT for 1 hr. Secondary Antibodies: Goat anti-mouse HRP at 1:5000, incubate at RT for 1 hr.

ELISA Validation of Spike 26P Antibodies with SARS-CoV-2 Gamma Variant Spike S1 Protein.Coating Antigen: SARS-CoV-2 spike S1 proteins of WT and Gamma variant (P.1), 1 μg/mL, incubate at 4°C overnight. Detection Antibodies: SARS-CoV-2 Spike 26P antibody, orb1238713, dilution: 0.3-1000 ng/mL, incubated at RT for 1 hr. Secondary Antibodies: Goat anti-mouse HRP at 1:5000, incubated at RT for 1 hr. SARS-CoV-2 Spike 26P antibody detects WT spike S1 protein (orb1231589), but not Gamma variant spike S1 protein.

ELISA Validation of Spike 26P Antibodies with SARS-CoV-2 Gamma Variant Spike S1 Protein.Loading: 50 ng of SARS-CoV-2 spike S1 proteins, WT and Gamma variant (P.1). Detection Antibodies: Spike 26P antibody, orb1238713, 1 μg/mL, incubated at RT for 1 hr. Secondary Antibodies: Goat anti-mouse HRP at 1:5000, incubated at RT for 1 hr. SARS-CoV-2 Spike 26P antibody detects WT spike S1 protein (orb1231589), but not Gamma variant spike S1 protein.

ELISA Validation of Spike 26P Antibodies with Mutant and WT Peptide. Coating Antigen: SARS-CoV-2 spike S1 peptides: WT (orb1231703) and Gamma variant (P.1) (orb1231659), 1 μg/mL, incubated at 4°C overnight. Detection Antibodies: SARS-CoV-2 26P antibody, orb1238713, dilution: 0.3-1000 ng/mL, incubated at RT for 1 hr. Secondary Antibodies: Goat anti-mouse HRP at 1:5000, incubated at RT for 1 hr. SARS-CoV-2 spike 26P antibody detects WT peptide (26P, orb1231703), but not Gamma variant spike S1 peptide (26S, orb1231659).
