On 31 December 2019, the World Health Organisation (WHO) was alerted of an outbreak of pneumonia in Wuhan City, China, caused by an unknown virus. The virus was sequenced and identified as a novel strain of Coronavirus one week later on 7 January 2020. It belongs to the same family of viruses which include Severe Acute Respiratory Syndrome (SARS) and Middle Eastern Respiratory Syndrome (MERS).|2019-nCoV is a positive-sense, single-stranded RNA virus which is thought to be of zoonotic origin. Symptoms of those infected include fever, dry cough, fatigue, shortness of breath and respiratory distress. Additionally, cases have resulted in renal failure, pneumonia and death. Those most seriously affected are individuals with already impaired immune systems, however approximately one quarter of otherwise well patients have required intensive care upon hospital admission.|Human-to-human transmission of the virus has been confirmed, with previous Coronavirus outbreaks (such as SARS) originating from similar environments in Asian markets, where humans and live animals are in close proximity.||Recombinant protein corresponding to Arg319-Phe541 from 2019-nCoV Spike RBD, fused to His-Tag at C-terminal, expressed in HEK293 cells.||Biological Activity:|Measured by its binding ability in a functional ELISA. Immobilized Recombinant 2019-nCoV Spike RBD-His at 2ug/mL (100ul/well) can bind Recombinant Human ACE2 with a linear range of 1.5-9.4ng/mL.||Storage and Stability:|Lyophilized and reconstituted products may be stored at -20°C. Stable for 6 months after receipt at -20°C. Reconstitute with sterile ddH2O. Aliquot to avoid repeated freezing and thawing. Store at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
