SARS-CoV-2 Spike Trimer (XBB.1) ELISA Kit (For Vaccine Development)

Multiple variants of SARS-CoV-2 are circulating globally and posting new challenges to human health. The variant B.1.1.7 identified in the United Kingdom (UK) carries a large number of mutations and is reported to spread more easily and quickly than other variants. The variant B.1.351 identified in South Africa ，P.1 identified in Brazil and B.1.617.2 in India show evidence of increased transmissibility and resistance to established immunity. A common mutation identified in the U.K, South African and Brazilian variants is N501Y, and the mutation identified in B.1.617.2 is T478K,which resides on the receptor-binding domain (RBD) of SARS-CoV-2 spike protein. To evaluate the impacts of the new variants, a rapid and effective assay kit detecting the levels of antibody against the mutant is in urgent need.

1. Store the unopened kit at 2-8°C upon receipt. 2. Locate the expiration date on the outer packaging and do not use reagents beyond their expiration date. 3. The opened kit should be stored according to the storage conditions listed in the Components Table. The shelf life of the opened kit is 30 days from the date of opening.

This assay kit employs a standard sandwich-ELISA format, providing a rapid detection of SARS-CoV-2 Spike Protein. The kit consists of microplate pre-coated with Anti-SARS-CoV-2 Spike protein Antibody, an SARS-CoV-2 Spike Protein as Control,biotin-Anti-SARS-CoV-2 Spike protein Antibody,HRP-Streptavidin and buffers.
