Purification of SPP containing complexes. (A) Schematic showing the protocol for the purification and iTRAQ-based mass spectrometry analysis of the SPP interacting proteins. (B) Purifications were analysed and compared by Western blot with anti-SPP antibody (left panel), demonstrating that the control purification protocol prevented SPP from being purified, and silver staining (right panel), showing the presence of several co-purified proteins that may represent novel SPP interacting proteins.
