FIG. 1.
Prototype reactivity patterns of HSV-positive human sera in the HSV-2-specific in-house confirmatory assay. (A) HSV-2-negative serum; (B) exclusively HSV-2-positive serum; (C) HSV-1- and HSV-2-positive serum. Strips were loaded with lysates of HSV-2-infected cells. Shown are the serum reactivity patterns observed after mock absorption (a) or preabsorption with HSV-1 (b), HSV-2 (c), or HSV-1 and HSV-2 (d).
