Abstract

LRP6 is a cell surface molecule that plays a critical role in the Wnt signaling pathway, and is implicated in numerous human diseases. Studies of cellular signaling mediated by LRP6 have relied on overexpression experiments, due to the lack of good monoclonal antibodies (mAbs) reactive with native LRP6 ectodomain. By using native recombinant LRP6 ectodomain fragment produced in mammalian expression system, we succeeded in developing a panel of anti-human LRP6 mAbs. Selected mAbs were capable of staining endogenous LRP6 on cell surface by using flow cytometry and immunofluorescence microscopy, and enriching detergent-solubilized LRP6 from cell lysate by immunoprecipitation.
