*This product has been discontinued!*
SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2) also known as 2019-nCoV (2019 Novel Coronavirus) is a virus that causes illnesses ranging from the common cold to severe diseases. SARS-CoV-2 Spike Protein is composed of S1 domain and S2 domain. A variant known as 20H/501Y.V2, from the B.1.351 lineage of coronaviruses, was first identified in South Africa in December. The World Health Organization named it Beta. The Key mutations of this variant include E484K, K417N, N501Y, which may help the virus latch on more tightly to human cells evade some kinds of antibodies.
