Expression of uPAR protein in different cell types. Western blotting of cell lysates was performed for an extended panel of cell types (HASM, undifferentiated HBEC, BEAS2B, THP1, PMN, PBMC) plus recombinant uPAR (ruPAR) using domain I specific (A) and domain II specific (B) antibodies to identify different variants. A β-actin antibody was used as a loading control (C). An ELISA assay, with a sensitivity of 30 pg/mL, was used to detect soluble uPAR in the culture supernatant where appropriate (D).
