comparison of vetl beta gal and wild-type viral proteins pulse-labeled at various times postinfection ( p.i . ) revealed ( i ) absence of a virus-induced 28-kda polypeptide , ( ii ) early expression of a large ( approximately 130-kda ) polypeptide which may be the etl-beta gal fusion protein , ( iii ) a delay in expression of early 35 and 40-kda polypeptides , and ( iv ) a 4- to 6-h delay in the expression of late proteins in vetl beta gal-infected cells .
