We help our customers to assemble SARS-CoV and SARS-CoV--2 S protein pseudotyped lentiviruses. These particles carry reporters that can be used for antiviral drug screening or the quantification of neutralizing antibodies. Customers can provide us with the reporter construct of your choice, and we will assemble particles within a week. Please contact us by email: info@signalwayantibody.com We also have several pre-assembled, concentrated (60 x concentrated) particles that are available for your initial testing. These particles are provided with a free sample of our proprietary SARS-CoV-2 Pseudovirus Infection Enhancer (CoV-2-PIE, Cat# CoV2-1) that can greatly promote productive viral infection. CoV-2-PIE can be used to facilitate the infection of a variety of host cells. CoV-2-PIE can enhance viral infection rates by 3 to 20 fold.
