The MV4;11:MSLN cell line generated by lentiviral transduction of MV4;11 cells using human MSLN had high MSLN expression with 132,290 anti-MSLN antibodies bound per cell, which was far greater than OVCAR-3, a MSLN-positive ovarian carcinoma cell line (Figure 1). The gene discussed is MSLN; the disease is ovarian carcinoma.
