SARS-CoV-2 (COVID-19) Spike RBD Protein, AY.1 / Delta plus variant, His tag (active)

Inhibition analysis of immobilized recombinant SARS-CoV-2 (COVID-19) Spike RBD Protein, AY.1 / Delta plus variant, His tag (delta plus variant) (GTX136333-pro) and SARS-CoV-2 (COVID-19) Spike RBD protein, His tag (active) (wild type) (GTX136090-pro) (coated at 2 μg/mL) binding to soluble recombinant Human ACE2 (ECD) protein, mouse IgG Fc tag (active) (GTX135683-pro) (1000 ng/mL) ACE2 binding was inhibited by increasing concentrations of SARS-CoV-2 (COVID-19) Spike RBD antibody [HL1002] (GTX635791) (0.09-66.67 nM). Bound ACE2 was detected by Goat Anti-Mouse IgG antibody (HRP) (GTX213111-01) (1:10000).

Functional ELISA analysis of immobilized recombinant SARS-CoV-2 (COVID-19) Spike RBD Protein, AY.1 / Delta plus variant, His tag (GTX136333-pro) (coated at 2 μg/mL) binding to soluble recombinant Human ACE2 (ECD) protein, mouse IgG Fc tag (active) (GTX135683-pro) (0.16-117.19 nM). Bound protein was detected by Goat Anti-Mouse IgG antibody (HRP) (GTX213111-01) (1:10000).

SARS-CoV-2 (COVID-19) Spike RBD (K417N, L452R, T478K Mutant) protein, His tag protein (GTX136333-pro, 0.5 μg) was separated by 12% SDS-PAGE, and the membrane was blotted with SARS-CoV-2 (COVID-19) Spike RBD antibody [HL257] (GTX635692) diluted at 1:5000.

1 μg of GTX136333-pro SARS-CoV-2 (COVID-19) Spike RBD (K417N, L452R, T478K Mutant) protein, His tag protein was analyzed using SDS-PAGE and stained with coomassie blue and captured by monochrome camera.
