Ea. Nelson et al., DIFFERENTIATION OF UNITED-STATES AND EUROPEAN ISOLATES OF PORCINE REPRODUCTIVE AND RESPIRATORY SYNDROME VIRUS BY MONOCLONAL-ANTIBODIES, Journal of clinical microbiology, 31(12), 1993, pp. 3184-3189
Monoclonal antibodies (MAbs) to two U.S. isolates of porcine reproduct
ive and respiratory syndrome (PRRS) virus were prepared. Two MAbs spec
ifically recognized a conserved epitope on the putative 15-kDa nucleoc
apsid protein of U.S. and European isolates of PRRS virus. Four other
MAbs recognized epitopes on the 15-kDa protein of U.S. but not Europea
n isolates of PRRS virus. Collectively, this indicates that PRRS virus
es contain both conserved and divergent epitopes on the 15-kDa viral p
rotein.
