Sandwich ELISA detection of recombinant SARS-CoV-2 (COVID-19) nucleocapsid protein, B.1.1.529 / Omicron variant, His tag (GTX136779-pro) using antibodies as below.

Capture: SARS-CoV-2 (COVID-19) nucleocapsid antibody [HL5511] (GTX635689) (5 μg/mL)
Detection: SARS-CoV-2 (COVID-19) nucleocapsid antibody [HL448] (HRP) (GTX635686-01) (1 μg/mL)

SARS-CoV-2 (COVID-19) nucleocapsid protein, B.1.1.529 / omicron variant, His tag (1 μg, GTX136779-pro) were separated by 12% SDS-PAGE, and the membrane was blotted with SARS-CoV-2 (COVID-19) nucleocapsid antibody [HL448] (GTX635686) diluted at 1:5000. The HRP-conjugated anti-rabbit IgG antibody (GTX213110-01) was used to detect the primary antibody.

GTX136779-pro SARS-CoV-2 (COVID-19) nucleocapsid protein, B.1.1.529 / omicron variant, His tag protein were analyzed using SDS-PAGE and stained with coomassie blue and captured by monochrome camera.

SARS-CoV-2 (COVID-19) nucleocapsid protein, B.1.1.529 / Omicron variant, His tag (0.5 μg), expressed by HEK293 cells (GTX136779-pro) or E. coli (GTX03400-pro), were separated by 10% SDS-PAGE, and the membrane was blotted with SARS-CoV-2 (COVID-19) nucleocapsid antibody [HL5410] (GTX635685) diluted at 1:20000. The HRP-conjugated anti-rabbit IgG antibody (GTX213110-01) was used to detect the primary antibody.

Sandwich ELISA detection of recombinant nucleocapsid protein(s) derived from different strains of SARS-CoV-2 virus (ie., Wild type; B.1.1.529 Omicron variant) using antibodies as below.

Capture: SARS-CoV-2 (COVID-19) nucleocapsid antibody [HL5511] (GTX635689) (5 μg/mL)
Detection: HRP-conjugated SARS-CoV-2 (COVID-19) nucleocapsid antibody [HL448] (GTX635686) (1 μg/mL)
Please notice that GTX635686 needs to be conjugated to HRP to function as the detection antibody when paired with GTX635689. Please contact us for custom HRP-conjugated antibody.

Indirect ELISA analysis performed by coating plate with recombinant SARS-CoV-2 (COVID-19) nucleocapsid protein, B.1.1.529 / Omicron variant, His tag (GTX136779-pro) (21.91-0.34 nM). Coated protein was probed with SARS-CoV-2 (COVID-19) nucleocapsid antibody [HL448] (GTX635686), SARS-CoV-2 (COVID-19) nucleocapsid antibody [HL5511] (GTX635689), SARS-CoV-2 (COVID-19) nucleocapsid antibody [HL5410] (GTX635685), SARS-CoV-2 (COVID-19) nucleocapsid antibody [HL455] (GTX635688), and SARS-CoV-2 (COVID-19) nucleocapsid antibody [HL344] (GTX635679) (1 μg/mL). Goat anti-rabbit IgG antibody (HRP) (GTX213110-01) (1:10000) was used to detect bound primary antibody.
