Figure 1. Western blot indicating an interaction between CTRP5 and CFH. The blot was probed with an hCTRP5 protein antibody. Lane A, with molecular weight markers from the same blot, is presented adjacent to lanes B-D: lane B is purified V5 tagged hCTRP5 protein; lane C is the immunoprecipitated (IP) fraction with the IgG control antibody and the western blot with the hCTRP5 antibody; lane D is the IP fraction with 1.5 μg human complement factor H antibody and western blot with hCTRP5 antibody.
