SARS-CoV-2 ADE-Causing Antibody (S9HC)

SARS-CoV-2 ADE-Causing Antibody (S9HC)

ELISA binding of SARS-CoV-2 ADE-Causing Antibody (S9HC) (GenScript, A02133) with recombinant SARS-CoV-2 Spike protein (ECD, His & Flag Tag) (GenScript, Z03481).
Coating antigen: SARS-CoV-2 Spike protein (ECD), 1 µg/ml.
SARS-CoV-2 ADE-Causing Antibody (S9HC) (GenScript, A02133) dilution start from 1 µg/ml.

SARS-CoV-2 ADE-Causing Antibody (S9HC)

Binding assay of SARS-COV-2 (Delta) to ACE2 mediated by antibodies
First, recombinant SARS-CoV-2 Delta spike protein (S1, His Tag) (GenScript, Z03612) was coated on the plate. Then, ADE-Causing antibody (GenScript, A02133), neutralizing antibody (GenScript, A02087) or non-neutralizing antibody (GenScript, A02038) were added to the wells after gradient dilution. Last, HRP conjugated ACE2 protein was added to the well to form the signals.
The result indicated that SARS-CoV-2 ADE-Causing Antibody (S9HC) (A02133) could enhance SARS-CoV-2 Delta spike protein binding with ACE2 compared with A02087 and A02038 which proved the ADE effect.

Specificity GenScript SARS-CoV-2 ADE-Causing Antibody (S9HC) reacts with SARS-CoV-2 Spike protein of wild type and delta variant. It can obviously enhance the SARS-COV-2 binding with ACE2.

Target Background SARS-CoV-2 ADE-causing antibody is a SARS-CoV-2 Spike protein antibody that can exacerbate the COVID-19 disease severity of patients. Antibody-dependent enhancement (ADE) may be involved in the clinical observation of patients with increased severity of symptoms and high levels of SARS-CoV-2 antibodies. It is reported [1] that the same antibodies against the NTD domain of the SARS-CoV-2 spike protein have an ADE effect by increasing the binding of ACE2 to the spike protein.
Synonyms Anti-SARS-CoV-2 ADE-Causing Antibody; SARS-CoV-2 Antibody-dependent enhancement Antibody; SARS-CoV-2 ADE response Antibody; SARS-CoV-2 Spike Antibody; SARS-CoV-2 ADE effect.
