Immunoblots of membrane preparations from all nineteen mutants.

<p>Three independent blots were performed with each mutant, using antibodies against subunits L, M, or for detection of N, anti-HA antibodies. For comparison, the null strain, BA14, and the wild type strain, BA14/pBA400, were included in each blot. Each lane contained 40 µg of protein. (A) Seven L mutants. (B) Six M mutants. (C) Six N mutants.
