What Is a Recombinant Antigen?
Coated antigens have evolved from one generation of whole virus lysates to three generations of dual-antigen sandwich reagents that are coated and labeled with genetic recombination and peptide antigens, with good sensitivity and specificity. Detection subtypes include HIV-1, HIV-2 and For HIV-1 subtype O, the window period is shortened from 10 weeks to 3-4 weeks.
