Delivery impact due to the Coronavirus Outbreak

With the COVID-19 outbreak in the world, many flights have been cancelled. In order for the customer to receive the goods properly, we use the FedEx Customized Freight (FCF) of Fedex which demands a higher fee. If the delivery fee is more expensive in your area, we will contact you by mail.

2019nCoV (SARS-CoV-2) RNA-Dependent RNA Polymerase (RdRP, Nsp12)


About Coronavirus RNA-Dependent RNA Polymerase (Coronavirus RdRP)

COVID-19 pandemic is caused by 2019nCoV (SARS-CoV-2) infection. 2019nCoV contains 16 Non-structure protein (Nsp1-Nsp16) that may be drugable targets for antiviral compounds discovery against COVID-191.

2019nCoV (SARS-CoV-2) RNA-Dependent RNA Polymerase (RdRP, Nsp12) is a multidomain RNA polymerase, which is the most conserved protein in coronaviruses. The coronavirus RNA-dependent RNA polymerase (RdRp) is essential for the viral replication and transcription.1
