Table 1: Heparin affinity and uPA inhibition of native and heated Serp-1 Proteins

Samples Proportion*(%) Heparin Affinity**(mM NaCl) uPA Inhibition
Native Serp-1
Unbound 5 0 No
Peak 1 95 555 Yes
Heated Serp-1
Unbound 6 0 No
Peak 1 86 400 No
Peak 2 8 680 Yes

* Protein concentration was measured using the Bio-Rad Protein Assay Kit
** Heparin affinity is given as the salt concentration required for elution
*** Measured in uPA activity assay
