FIGURE 7.
Binding analysis of MP-4 with trypsin and chymotrypsin by SPR. A, SPR sensorgram for the binding of MP-4 (ligand) to trypsin (analyte) immobilized on the surface of a CM5 chip. The ligand was tested in the concentration range from 16 to 0.125 μm. B, binding of MP-4 (ligand) to chymotrypsin (analyte), where chymotrypsin was used in the range from 32 to 0.125 μm. Shown are the equilibrium rate constant, Rmax, and χ2 value for MP-4·trypsin and MP-4·chymotrypsin complex over the corresponding sensorgram. RU, response units.
