[Oligopeptide maps of the matrix protein of a temperature-sensitive mutant (TS 303) of the fowl plague virus]

Oligopeptide maps of M proteins of "wild" fowl plague virus (FPV) and a temperature-sensitive mutant of FPV were compared with respect of gene. In maps of M proteins labeled with 14C-chlorella hydrolysate and 35S-methionine the mutant virus was found to lack one of oligopeptides present in maps of M proteins of the "wild" virus. The electrophoretic mobility of M proteins of ts 303 and FPV in 25% polyacrylamide gel was similar.
