The Analysis of the Struetural Polypeptides of Rabbit Hemorrhagic Disease Virus

The RHDV virion comprised six sturctural polypeptides as analysed by sodium dodecylsulfate-polyacrylamide gel electrophoresis, including A(molecular weight 60.12 kD),B(58. 27kD),C(54.74kD),D(53. 01kD),E(51. 10kD) and G(25. 90kD).The major polypep-tide A(including polypeptide B constituted about 54.7% of the total viral proteins. polypep-tide C constituted 1 7.7%, polypeptide D and E were about 22.7%and polypeptide G wereabout 4.9%. By western blotting with rabbit antiserum,polypeptides A、B、C、D、E and Gwere detected. by using monoclonal antibodies AA8-1、CG4-1 and CH3-1,all the six polypep-tides could be recognized,indicating that these polypeptides shared extensive antigenic rela-tionship.
