a, Flow cytometry demonstrates similar intracellular expression of wild-type FI and mutants in transiently transfected HEK293 cells following treatment with Brefeldin A. b, Western blot of purified cell culture supernatants following transient transfection with wild-type (wt) or mutant CFI His-tagged plasmids. Images are representative of five independent experiments
