Detection Kit for Neutralization Antibody of SARS-CoV-2 (Competitive ELISA)

For Research Use Only. Not for use in diagnostic procedures.

Product Description

The Detection Kit for Neutralization Antibody of SARS-CoV-2 is a competitive Enzyme-Linked Immunosorbent Assay (ELISA) intended for detection of total neutralization antibodies to SARS-CoV-2 in serum/plasma. The receptor-binding domain (RBD) of the SARS-CoV-2 S protein, which is responsible for recognizing the cell surface receptor, angiotensin-converting enzyme-2 (ACE2). Current research indicates that the RBD strongly interacts with the human ACE2 receptor, leading to endocytosis of the virus into the host cells of the deep lung and viral replication.
