Abstract:
A technique, using indirect immunoperoxidase antibody (IPA), was developed for the detection of IgG antibody to Hantaan virus. The same protein A-peroxidase conjugate was used with mouse, rat and human sera. The IPA technique employs glass slides with air-dried gamma-ray-inactivated and acetone-fixed Hantaan-infected Vero-E6 cells. Antibody titers detected by IPA was comparable to those detected by the indirect fluorescent antibody technique.
