From: Possible Involvement of Keratinocyte Growth Factor and Its Receptor in Enhanced Epithelial-Cell Proliferation and Acquired Recurrence of Middle-Ear Cholesteatoma

Figure 1

Western blot analysis of keratinocyte growth factor (KGF) and KGF receptor (KGFR) in rhKGF, rhKGFR, and human middle-ear cholesteatoma. a, rhKGF protein (lane 1 0.5 μg) and lysate of human middle ear cholesteatoma (lane 2 25 μg). Lanes 1 and 2, Reacted with 0.5 μg/mL anti-KGF antibody. b, rhKGFR protein (lane 1 0.25 μg) and lysate of human middle ear cholesteatoma (lanes 2 and 3 12.5 μg). Lanes 1 and 2, Reacted with 0.05 μg/mL anti-KGFR antibody. Lane 3, reacted with 0.05 μg/mL anti-KGFR antibody preincubated with KGFR (10–1) peptide (500-fold molar excess).
