SARS-CoV-2 Spike Antigen B.1.351 (South African Variant)

All viruses undergo fast mutations and adept quickly to the countermeasures that the immune systems creates against them. SARS-CoV-2 of the COVID-19 pandemic is no exception here. Spike protein of the mutant strain B.1.351, also commonly known as the “South Africa Variant”. It is a full-length protein, which is active in its native trimeric form, that is stabilized in LMNG detergent.
