Figure Legend Snippet: Figure 1. Physical interactions between TRF2 and BER proteins. A, increasing concentrations of various proteins were spotted in replicate (0.6, 0.8, 0.9, and 1 ng) on a grid of the Discover-Light Protein Array membrane and then hybridized with TRF2 protein (10 ng/mL). After washing, bound TRF2 protein was detected by Western blotting with an anti-TRF2 antibody. B, coimmunoprecipitation of TRF2 and Pol h. HeLa whole-cell extracts (500 ng) were immunoprecipitated with either rabbit anti-TRF2 (lane 3) or control IgG (lane 4) antibodies. The immunoprecipitates were analyzed by SDS-PAGE and Western blot analysis with anti–Pol h or anti-TRF2 antibodies as indicated. TRF2 (lane 1) and Pol h (lane 6) were loaded as markers and positive controls. Input, 10% loaded (lane 2). C, coimmunoprecipitation of TRF2 and FEN-1. HeLa whole-cell extracts (500 ng) were immunoprecipitated with either rabbit anti-TRF2 (lane 3) or control IgG antibodies (lane 1). The immunoprecipitates were probed with anti-FEN-1 or anti-TRF2 antibodies as indicated. Input, 10% loaded (lane 2).

Eluted proteins were separated by SDS-PAGE, transferred to a membrane, and stained with amido black to ensure equal loading of the various TRF2 fragments. The membrane was probed with mouse anti–Pol h or rabbit anti-FEN-1 antibodies.
