Figure 3: Sub-cellular localization and biological processes of lipid raft proteins from MEC1 cells identified by LC-MS/MS. i) Sub-cellular localization, and ii) biological processes based on the Human Protein Reference Database (www.hprd.org), PubMed (www.uniprot.org) and BioMyn (www.biomyn.de). (A), proteins isolated using sucrose gradient centrifugation (B), proteins identified by MβCD-treatment (C), and proteins identified from LR following immuno-precipitation of CD20 with rituximab.
