AdipoGen SARS-CoV-2 Neutralizing Antibodies Detection Kit (96 wells)
SARS-CoV-2 contains 4 structural proteins, including Envelope (E), Membrane (M), Nucleocapsid (N) and Spike (S), which is a transmembrane protein, composed of two subunits S1 and S2. The S1 subunit contains a receptor binding domain (RBD), which binds to the cell surface receptor Angiotensin-Converting Enzyme 2 (ACE2) present at the surface of epithelial cells, causing mainly infection of human respiratory cells.The SARS-CoV-2 Neutralizing Antibodies Detection Kit contains key reagents required to test the presence of functional neutralizing antibodies against SARS-CoV-2 present in the serum or plasma. It is an easy and fast alternative to the classical neutralization assay using Vero E6 cells. This Detection Kit is based on a colorimetric reaction, which measures the binding of the RBD of the Spike S protein from SARS-CoV-2 to its human receptor ACE2.

AURORA BIOLABS LLC SARS-CoV-2 Mpro Assay, 96 rxn
Mpro of Severe acute respiratory syndrome Coronavirus 2 (SARS-CoV-2 Mpro, also referred to as SARS-CoV-2 Main protease, SARS-CoV-2 3CL protease) plays an essential role in viral replication by processing the polyproteins 1ab at 11 cleavage sites. Inhibiting the activity of this enzyme would block viral replication, making it a promising target for anti-coronaviral therapeutic agents. The assay is fast and convenient and requires just two steps. In the first step, the Mpro enzyme is preincubated with the compound for 30 minutes. The reaction is initiated by adding substrate solution at the second step. Fluorescent intensity is measured with a fluorescent plate reader at the excitation wavelengths of 340-360 nm and emission wavelengths of 460-480 nm.
