From: Expression of growth factor receptors and targeting of EGFR in cholangiocarcinoma cell lines
IHC for growth factor receptors on different CC cell lines. Immunostaining of EGFR on EGI-1 (A), HuH28 (C), OZ (E) and TFK-1 (G) with the according isotype staining (B, D, F and H). Immunostaining of HGFR (I), IGF1R (J), IGF2R (K), VEGFR1 (L), VEGFR2 (M) and VEGFR3 (N). IHC revealed expression of the growth factor receptors tested in all human CC cell lines. ABC procedure (A-I, K-M) and APAAP method (J and N). Original magnification × 200.
