Extracellular protein extracts from MFS and IM were depleted for albumin and IgG, separated by SDS-PAGE, in-gel digested with trypsin and analyzed by LC-MS. Shown are the top 30 proteins identified in MFS. Proteins that were also identified in IM are indicated with a + sign. Many forms of keratins and IgGs were also identified within the initial top 30 protein list, but for the sake of clarity, they have been removed.
