Antibody specificity.

<p>Rabbit polyclonal antibody raised against specific synthetic peptide at N-terminal (P2) and C-terminal (P3) of ERRα and ERRγ (pG), as described before was tested with Western blotting. A. P2 and P3 antibodies. B. pG and c-Myc antibodies. The cell extract was prepared from HeLa cells which was overexpressed with expression construct of ERRα and ERRγ with or without myc tag. β-actin serves as loading control.
