The “Western blotting technique” has been applied to rotavirus isolates from bovine and porcine species. Five to six polypeptides were identified for both bovine and porcine rotavirus with estimated molecular weights (MW) of 150-160K, 140-145K, 99K, 60-65K, 40-49K and 30K, of which the 40-49K polypeptide band was the strongest. These results were obtained when the virus samples were dissociated by immersing in boiling water for 3 mins before SDS-PAGE. When the virus samples were heated for 10 mins at 56°C instead, a total dissociation of the virus proteins did not occur and only two polypeptides with estimated MW of 80-85K and 95-100K appeared, of which the 80-85K polypeptide was the most intense. The possibility that the 80-85K polypeptide consists partly of the 40-49K polypeptide is discussed.
