Does the drugstore in Taishi Town, Lintao County have antigen?
Yes Antigen testing generally refers to novel coronavirus antigen testing reagents, and pharmacies have novel coronavirus antigen testing reagents. Antigen (abbreviated as Ag) is any substance that can induce immune response. Foreign molecules can be recognized by immunoglobulins on B cells, or treated by antigen-presenting cells and combined with major histocompatibility complexes to reactivate T cells and trigger a sustained immune response.
