FT surface-bound huPLG can be converted to plasmin. FTLVS was incubated with huPLG at a concentration of 96 μg/mL. After removal of unbound huPLG, a chromogenic plasmin substrate (D-VLK-pNA), tissue PLG activator (tPA), or both were then added to test the proteolytic ability of each sample preparation. Conversion of the chromogenic substrate was measured by comparison of Δ405 nm. The results shown are representative of 3 experiments of similar design. Bars indicate +/- SEM in triplicate. Statistical analysis was performed via one-way ANOVA using a Dunnett's Multiple Comparison post-test (*** P < .001).
