Simultaneously binds to anti-S and anti-N protein antibody with high affinity
RBD-N protein chimera was added into the wells coated with anti 2019-nCoV N-protein hIgG antibody (C19NP-60H). Binding was detected by incubating the wells with HRP-conjugated anti 2019-nCoV Spike Protein hIgG antibody (C19S1-60DH).
Detection with Anti-SARS-CoV-2 S Protein Antibody
Detection with Anti-SARS-CoV-2 N Protein Antibody
ELISA plates were coated with recombinant SARS-CoV-2 proteins. HRP-conjugated specific antibodies were added to detect the binding. RBD-N chimera protein demonstrated specific binding to anti-S and anti-N antibody with higher affinity comparing to individual S or N protein.
The sensitivity of ELISA using new antibody pair is significantly increased comparing to previous assay.
The ELISA using new antibody pair has limit of detection (LOD) at picomole level.
