Spike Variants (SARS-CoV-2) Pseudotyped Lentivirus Pack (Luciferase Reporter)

The pandemic coronavirus disease 2019 () is caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). As the first step of the viral replication, the virus attaches to the host cell surface before entering the cell. The viral Spike protein recognizes and attaches to the Angiotensin-Converting Enzyme 2 (ACE2) receptor found on the surface of type I and II pneumocytes, endothelial cells, and ciliated bronchial epithelial cells. Drugs targeting the interaction between the Spike protein of SARS-CoV-2 and human ACE2 may offer protection against the viral infection. Numerous SARS-CoV-2 variants have been identified so far. These variants contain a number of mutations that may increase morbidity and mortality and allow the virus to spread more easily and quickly than the original strain.BPS Bioscience has launched a series of Spike Variants (SARS-CoV-2) Pseudotyped Lentivirus (Luc reporter). The Spike (SARS-CoV-2) Pseudotyped Lentiviruses were produced with SARS-CoV-2 Spike Variant (see below for mutation details) as the envelope glycoproteins instead of the commonly used VSV-G. These pseudovirions contain the firefly luciferase gene driven by a CMV promoter, therefore, the spike-mediated cell entry can be measured via luciferase activity. The Spike Variants (SARS-CoV-2) Pseudotyped Lentivirus Pack (Luciferase Reporter) contains a collection of 12 Spike variants (SARS-CoV-2) Pseudotyped lentivirus (Luc reporter). It is a great tool to screen for variant-specific antibodies or to test the binding or efficacy of drug candidates against the different Spike variants. The Spike (SARS-CoV-2) pseudotyped lentiviruses can be used to measure the activity of neutralizing antibody against SARS-CoV-2 infection in a Biosafety Level 2 facility.
