Figure 1Soluble alkaline phosphatase (ALP) activity is inhibited by MABP covalently attached to TGA-fixed collagen: the linear relationship between ALP concentration (U) and activity observed over a TGA crosslinked substrate (closed circles) was significantly reduced by concurrent covalent linkage of MABP (open circles, p<0.001) and further depressed by sequential linkage of MABP (closed triangles, p<0.001).
