Figure 2. The expression difference of transferrin receptor between glioblastoma and astrocyte cells.

(A and B) The proteins of U87, A172 and NHA cells were extracted without any treatment. The expression of proteins was analyzed by Western blot analysis with indicated antibodies. The bands were then quantified by ImageJ software. Results are the mean ± S.E.M. (n=3 for each group). *P<0.05; **P<0.01 versus control group.
