Real time observation of the binding of herpes simplex virus type 1 (HSV-1) to immobilized heparan sulfate and the neutralization of HSV-1 by sulfonated human immunoglobulin.

ABSTRACT

A real time biomolecular interaction assay system involving an optical sensor was applied to quantitative analysis of the binding of herpes simplex virus type 1 (HSV-1) to immobilized heparan sulfate, a cellular receptor component of HSV-1, and the neutralization antibody titer against this virus with a commercially available sulfonated human immunoglobulin preparation. The virus titer in a viral solution and the neutralizing antibody titer in the human immunoglobulin preparation could be successfully estimated in a short time with this system without any difficult cell culture.
