[Electrophoretic characteristics of the soluble glycoproteins of the A-2 and MK-25 strains of Aujeszky's disease virus].

Studied were soluble glycoproteins of the Aujeszky's disease virus strains--the virulent A-2 one and its IUDR-resistant MK-25 mutant, following purification via affinity chromatography. Two protein bands were found through polyacrylamide gel. The molecule weight of the glycoproteins isolated from A-2 strain was 67,000 daltons, and that of the MK-25 ones--42,000 daltons. It was shown to be close to the molecule weight of two structural viral proteins. These properties of theirs as well as the capacity of the antisera to neutralize the Aujeszky's disease virus made it reasonable to believe that the isolated glycoproteins were in fact soluble structural viral glycoproteins.
