SARS-CoV-2 (COVID-19) Spike S2 (ECD) 蛋白, B.1.1.7 / Alpha variant, His tag

Sandwich ELISA detection of recombinant SARS-CoV-2 (COVID-19) Spike S2 (T716I, S982A, D1118H Mutant) (ECD) protein, His tag (GTX136023-pro) using SARS-CoV / SARS-CoV-2 (COVID-19) spike antibody [1A9] (GTX632604) as capture antibody at concentration of 5 μg/mL and SARS-CoV-2 (COVID-19) Spike S2 antibody [HL237] (GTX635693) as detection antibody at concentration of 1 μg/mL. Rabbit IgG antibody (HRP) (GTX213110-01) was diluted at 1:10000 and used to detect the primary antibody.
