SARS-CoV-2 Spike Antigen B.1.525 (UK/Nigerian 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.1.525 is a full-length protein, which is active in its native trimeric form, that is stabilized in LMNG detergent.
