High quality “Stealth Omicron” BA.2 antigens are all in stock

 


BA.2, a subvariant of Omicron, has been identified in at least 69 countries and is expected to be increasingly prevalent around the world. It has about 20 mutations that set it apart from BA.1 and does not contain a mutation that distinguishes Omicron from other variants in genetic PCR tests, this is the reason why some researchers have described BA.2 as “stealth Omicron”.

To support the global response for BA.2, ACROBiosystems has developed a series of BA.2 antigens, including Spike trimer, RBD, NTD, S1, and N protein with high purity.
