The method depends on quantification of the release of specifically radiolabelled activation peptides from bovine trypsinogen. The assay is applicable to biological fluids such as serum 95568 3.4.21.9 0.045 - - 95574 3.4.21.9 1.36 - - 95572 3.4.21.9 220 - thioredoxin-human epidermal growth factor fusion protein as substrate 683172 3.4.21.9 330 - purified native enzyme, pH 5.0, 25°C 718100 3.4.21.9 2100 - thioredoxin/human epidermal growth factor fusion protein as substrate 683172 3.4.21.9 8000 - rEKL/His, Gly-Asp-Asp-Asp-Asp-Lys-beta-naphthylamide substrate 669550 3.4.21.9 9000 - rEKL, Gly-Asp-Asp-Asp-Asp-Lys-beta-naphthylamide substrate 669550
