Figure 3From: Bone sialoprotein does not interact with pro-gelatinase A (MMP-2) or mediate MMP-2 activation Interactions between BSP peptides and proMMP-2. proMMP-2 (333 nM) was incubated with nM amounts of BSP peptides. Emission scans were obtained after each addition of BSP (excitation wavelength = 295 nm). Emission spectra show that titration of proMMP-2 with each BSP peptide yielded proportional quenching of the proMMP-2 emission spectra.Back to article page
