Description
Plasminogen's kringle domains mediate critical anti-angiogenic signaling, and this tag-free partial construct (residues 98–356) delivers a specific activity of 5.5 × 10⁵ IU/mg validated through anti-proliferation, anti-migration, and anti-angiogenesis assays using endothelial cells. The absence of any fusion tag eliminates steric interference with functional epitopes, making this protein appropriate for kinetic parameter analysis (Km, Vmax, kcat), inhibitor screening with reliable IC50 determination, and substrate specificity profiling in angiogenesis-related cancer research. Expressed in *E. coli*, the construct achieves >95% purity by SDS-PAGE and endotoxin levels below 1.0 EU/μg, satisfying the quality thresholds commonly required for cell-based drug candidate evaluation, positive controls in enzyme-linked functional assays, and structural studies such as crystallography where homogeneity is essential.
