Is able to inhibit all four classes of proteinases by a unique 'trapping' mechanism. This protein has a peptide stretch, called the 'bait region' which contains specific cleavage sites for different proteinases. When a proteinase cleaves the bait region, a conformational change is induced in the protein which traps the proteinase. The entrapped enzyme remains active against low molecular weight substrates (activity against high molecular weight substrates is greatly reduced). Following cleavage in the bait region, a thioester bond is hydrolyzed and mediates the covalent binding of the protein to the proteinase.

Figure 5. Comparison of the re-probed ability of PVDF membrane and NC membrane. Te pooled sera proteins (3.0, 1.5, 0.7, 0.3 and 0.1 μg) were separated by 8% SDS-PAGE, and transferred to PVDF membranes (up) and NC membrane (down), respectively. (a) Staining with AAL and then re-probed with PHA-E; (b) staining with ApoA1 and then re-probing with IgG; (c) Staining with PHA-E and then re-probing with A2M; (d) staining with A2M and then re-probing with PHA-E. Band intensities were statistically analyzed (n=3 individual experiments) and compared using Image Lab sofware (Bio-Rad Laboratories) and GraphPad Prism version 6. Pink bar, PVDF membrane; Blue bar, NC membrane. Band intensities were analyzed *Signifcantly diferent p<0.05, **p<0.01. N.S., not signifcant. All values are means±S.E. (error bars)....
