FPLC profile of Q-Sepharose chromatography for acidic proteins extracted from the mouse long bone. Protein extracts was separated and collected into continuous 120 fractions for biochemistry analyses. a: FPLC chromatogram for bone extracts from D452A-DSPP transgenic mice. b: FPLC chromatogram for bone extracts from wild type mice. Western immunoblotting and Stains-All staining illustrated that the fractions between the two arrows (fractions 20 to 58) in(a) contained DSPP and its fragments, DSP and DPP.
