Rabies virus isolates from terrestrial animals in six areas of the United States were examined with a panel of monoclonal antibodies to nucleocapsid proteins. Characteristic differences in...
Serodiagnosis of rabies by dot immunobinding assay.
Heberling, R L, Kalter, S S, Smith, J S, Hildebrand, D G
A dot immunobinding assay that uses inactivated antigen for the detection of rabies viral antibodies was compared with the rapid fluorescent focus inhibition test. Results of testing pre- and...
Microneutralization test for rabies virus based on an enzyme immunoassay.
Mannen, K, Mifune, K, Reid-Sanden, F L, Smith, J S, Yager, P A, Sumner, J W, ...
We have developed an enzyme immunoassay for rabies virus by using acetone-fixed infected cell cultures as the antigen. This test was used to demonstrate virus-neutralizing antibodies in human and...
