SARS-CoV-2 surrogate virus neutralization test
VIRUS
SARS-CoV-2 surrogate virus neutralization test in nasal fluid specimens against the ancestral, Delta, and Omicron BA.2 HRP-conjugated RBD proteins were determined using a SARS-CoV-2 surrogate virus neutralization test (cPass SARS-CoV-2 neutralization antibody detection kit, GenScript; A02087, Z03614, and Z03741). Nasal fluid specimens were diluted ~ tenfold in sample dilution buffer, and then the SARS-CoV-2 inhibitory effects were measured according to the instruction manual and reported as % inhibition against SARS-CoV-2.
