Description

General description

designed to simplify the identification and characterization of SARS-CoV-2 inhibitors.

Application

The SARS-CoV-2 Inhibitors Screening Kit is a convenient tool, designed to simplify the identification and characterization of SARS-CoV-2 inhibitors.The crutial interaction between the SARS-CoV-2 and human cells accrues through the protein-protein interaction of human receptor ACE2 and viral protein Spike – S protein. The receptor binding domain (RBD) of S protein is the domain that specifically binds to ACE2. Our SARS-CoV-2 Inhibitors Screening Kit includes both human ACE protein and viral RBD of S protein. The kit is based on a colorimetric ELISA, where biotinylated ACE2 (ACE2-biotin) and Extravidin^®-peroxidase are used to detect the ACE2:RBD interaction. One molecule of Extravidin^® binds four molecules of biotin by a non-covalent interaction that is essentially irreversible. Binding visualization is achieved by using o-Phenylenediamine dihydrochloride (OPD), a peroxidase substrate with absorbance at 450 nm.

Inhibitors and neutralizing antibodies against RBD that interfere with the ACE2:RBD interaction will result in reduced colorimetric signal.

Biochem/physiol Actions

SARS-CoV-2 - Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) belongs to Coronaviridae (CoVs) - a large family of viruses that usually cause mild to moderate upper-respiratory tract diseases.1 CoVs are single-stranded RNA viruses. They have a high mutation rate and are therefore highly diverse.1 Their hosts include human and non-human mammals, as well as birds.1

SARS-CoV-2 infects cells which express angiotensin converting enzyme 2 (ACE2).2 ACE2 binds to the viral envelope-associated spike (S) protein as a cellular receptor, following proteolytic cleavage of both S and ACE2 by serine proteases.3 S protein is believed to be the target of neutralizing antibodies because it is the main trans-membrane glycoprotein responsible for receptor-binding and virion entry.4

The S protein is a trimeric protein. During the binding to ACE2, S protein undergoes a substantial structural rearrangement to facilitate the fusion of the viral membrane with the host cell membrane.5 The receptor binding domain (RBD) of S protein is the domain that specifically binds to ACE2. RBD is the major target for neutralizing antibodies for coronaviruses6, and anti-RBD antibodies likely correlate with virus neutralization.7
