SARS-COV-2(2019-nCoV) Spike Protein (S-RBD), His Tag Recombinant Protein

COVID-19, a novel pathogenic coronavirus (2019-nCoV or SARS-CoV2) that causes the COVID-19 pandemic respiratory illness and spread globally rapidly. The SARS-CoV-2 (2019-nCoV) Spike Protein (S-RBD) has been identified as the key viral element allowing the virus docking to the ACE2 surface membrane receptor. So the SARS-COV-2(2019-nCoV) Spike Protein (S-RBD) is a key target for urgently needed vaccines, therapeutic antibodies, and diagnostics.

BrainVTA can provide SARS-COV-2(2019-nCoV) Spike Protein (S-RBD) with high-quality for small or large scale.
