SARS-CoV-2 Antigen Variants

SARS-CoV-2 has experienced a variety of mutations in the RBD domain of the spike protein which has led to the development of numerous variants in recent months. Some of the mutations occur in more than one variant and hold great value since they alter the protein structure which enhances evasion of the immune system and increased transmissibility. BioServUK offers a range of antigens including the latest Omicron Variant (B.1.1.529), Indian Delta Variant (B.1.617.2), UK Variant (B.1.1.7), South African Variant (B.1.351) and Brazil Variant (P.1).
