Figure 5. Recognition of the wild-type two-chain HGF by the t8E4 antibody.

Figure 5

The culture media from tcHGF-PA (tc), scHGF(Xa)-PA (sc), or mock (m)-transfected HEK293T cells were immunoprecipitated with either t8E4, t1E4, or NZ-1, followed by the SDS-PAGE and Coomassie staining. The wild-type HGF protein was fully converted into two-chain species because of the cleavage by serum-derived protease during the expression, while the engineered “Xa” version remained as single chain species under the same condition. Because of the non-reducing condition employed here, however, both proteins migrated as an ~75-kDa band (arrowhead).
