Binding of scFvMTBHsp70 or MTBHsp70 to BR5FVB1 ovarian cancer cells or 40L mesothelioma cells, as determined by flow cytometry, is shown in Figure 1C and D. Binding of scFvMTBHsp70 to MSLN-expressing tumor cells was almost completely inhibited by preincubation of scFvMTBHsp70 with recombinant human MSLN. Here, MSLN is linked to neoplasm.
