Structural immuno-analysis of human and porcine interferon gamma: identification of shared antigenic domain.

We examined the antigenic resemblance between human (h) and porcine (p) interferon (IFN)-gamma by binding (ELISA) and neutralization assays. The murine polyclonal antisera and sets of murine monoclonal antibodies (mAbs) raised against either IFN were tested in confrontation with recombinant IFNs of either species, and with site-specific mutants of hIFN… (More)
