Figure 3From: Aggregation and retention of human urokinase type plasminogen activator in the yeast endoplasmic reticulumHalo-forming ability of S. cerevisiae (Sc) and H. polymorpha (Hp) transformants expressing different uPA variants. Yeast transformants were patched on fibrin-containing plates and incubated for 20 h (H. polymorpha) or 40 h (S. cerevisiae).Back to article page
