![ELISA: SARS-CoV-2 Spike RBD Antibody (T4P3-B7) - VHH [NBP3-12842] - A direct ELISA was performed using SARS-CoV-2 Spike RBD recombinant protein as coating antigen at 1 ug/mL and the anti-SARS-CoV-2 Spike RBD antibody (NBP3-12842) as the capture antibody, following by anti-cMyc-tag antibody at 1 ug/mL. Secondary: Goat anti-mouse IgG HRP conjugate at 1:5000 dilution. Detection range is from 0.3 ng/mL to 1000 ng/mL. SARS-CoV-2 Spike RBD Antibody, NBP3-12842 can detect spike RBD protein at 10 ng/mL.](http://images.novusbio.com/fullsize/SARS-CoV-2-Spike-RBD-Antibody-T4P3-B7-VHH-ELISA-NBP3-12842-img0001.jpg "ELISA: SARS-CoV-2 Spike RBD Antibody (T4P3-B7) - VHH [NBP3-12842] - A direct ELISA was performed using SARS-CoV-2 Spike RBD recombinant protein as coating antigen at 1 ug/mL and the anti-SARS-CoV-2 Spike RBD antibody (NBP3-12842) as the capture antibody, following by anti-cMyc-tag antibody at 1 ug/mL.
