Kinetics of mi protein expression in activated mast cells. Immunoprecipitates of [35S]-methionine–labeled mi derived from IL-3–stimulated (A), IgE-DNP–stimulated (B), or IL-4–stimulated (C) MC-9 cells, using antimouse mi antiserum. Duplicate samples are presented. One representative experiment of three performed is shown. Immunoprecipitates of [35S]-methionine–labeled myosin derived from IL-3–stimulated MC-9 cells using antimyosin antiserum is shown in (D). One representative experiment of two performed is shown. Samples were analyzed by SDS-PAGE.
