SARS-CoV-2 Spike Antigen B.1.1.529 (Omicron Variant) 1mg


1 mg


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. During the pandemic multiple mutant strains arose. Spike protein of the mutant strain B.1.1.529, also commonly known as the “Omicron Variant”. It is a full-length protein, which is active in its native trimeric form, that is stabilized in LMNG detergent.
