Binding of LE2E9 to native or Arg2150His C1 and C1C2 domains.
Native and Arg2150His recombinant fVIII C1 domain (A) or C1C2 domains (B) labeled with [35S]methionine and expressed in reticulocyte lysates were incubated for 2 hours at 4°C with LE2E9 (LE) bound to Protein A Sepharose. After washing, bound material was eluted by SDS-buffer and analyzed by SDS-PAGE, followed by autoradiography. Controls included the human monoclonal antibody, BO2C11 (BO), and normal donor polyclonal IgG antibodies (Wi). The experiments were repeated 3 times with similar results.
