Comparison of the protein composition of two plaque variants of Sendai virus.

The protein composition of plaque variants of Sendai virus were compared by slab polyacrylamide gel electrophoresis. The RL and RS variants displayed clearly different P-protein mobilities; the P protein of the RS variant migrated faster than that of the RL variant, while no difference was found with proteins L, HANA, NP, F1 and M. These protein patterns differed from those of the Fushimi and Z strains.
