Figure 3.
The co-expression status of HAI-1 and HAI-2 at protein levels in seven matriptase-expressing neoplastic B-cells. One million (106) cells from seven different matriptase-expressing neoplastic B-cell lines, as indicated, were analysed by immunoblot for protein levels of matriptase (A), the two species of HAI-2 (B and C), and HAI-1 (D). The expression of the highly glycosylated HAI-2 was also assessed with longer X-ray film exposure, as indicated.
