Figure 4.

Cumulative plasminogen activation by Pla-Epo hybrid proteins expressed in E. coli. (A) Pla-Epo hybrids with cumulative substitutions towards Pla. (B) Pla-Epo hybrids with cumulative substitutions towards Epo. Inserts show the plasmid constructs (see Table 1). The data are average from two independent assays with duplicate samples, and standard deviations are shown.
