Figure 2From: Bone sialoprotein does not interact with pro-gelatinase A (MMP-2) or mediate MMP-2 activation Tryptophan fluorescence profile. proMMP-2 (333 nM) was incubated with nM amounts of native BSP. Emission scans were obtained after each addition of BSP (excitation wavelength = 295 nm). Emission peak was at 335 nm.Back to article page
