Product information "SARS CoV-2 Spike B.1.351 Mutation RBD domain"
Product Type: Mutant Spike Protein
Protein Sequence: RB Domain
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. To help the science combat these mutants Cube Biotech offers the RB-Domains of these mutant SPIKE proteins.

That is the full Receptor-Binding Domain of the SPIKE surface protein SARS-CoV-2 of the mutant strain B.1.351, also commonly known as the "SA / South Africa mutant". Its individual mutations are listed in the "features" table below.
Further SPIKE related products by Cube Biotech include:
    1. Full-length & active SPIKE protein of mutant Strain B.1.351 stabilized in LMNG
    2. The RB-Domain of SPIKE mutant strain B.1.1.7, also known as the "UK mutant"
    3. The RB-Domain of SPIKE mutant strain P.1, also known as the "Brazil mutant"
    4. The "original" SPIKE protein in LMNG.
    5. Anti-SPIKE antibodies
