Title	Proteome of DiFi and CC-CR supermeres purified by FPLC with or without additional affinity purification for TGFBi
Description	The cell seretome is diverse and contains extracellular secreted vesicles (EVs) as well as non-vesicular extracellular nanoparticles (NVEPs) called exomeres and supermeres, all of which carry different kinds of cell signaling cargos. One supermere enriched cargo is transforming growth factor beta induced (TGFBi) protein. We have created TGFBi-neon green-His tagged expressing cell lines in the microsatellite stable (MSS) colorectal cancer cell line DiFi and another one in CC-CR cells with microsatellite instability (MSI). We have developed a fast protein liquid chromatography (FPLC) method for isolating EVs, exomeres and supermeres from biofluids. We used either FPLC or FPLC and then nickel columns that bind His tags to isolate supermeres from DiFi or CC-CR cells. We utilized a proteomics approach acquiring LC-MS/MS data to compare FPLC to FPLC and His tagged TGFBi-containing purified supermeres from DiFi and CC-CR cells. This was done using hollow fiber 3D bioreactor production of conditioned media from these cell lines.
