Characterization of the high-molecular-weight factor H associated with the R1210C mutation. a, 10% SDS-PAGE of the factor H (fH) proteins purified from patient HUS29 and control individual N3. Samples were reduced with 10% β-mercaptoethanol. A gel stained with 1% Coomassie is shown. b, Western blot analyses of reduced and nonreduced factor H proteins purified from patient HUS29 and control individual N3, using a rabbit anti-HSA polyclonal antibody. c, SDS-PAGE analysis of the wild-type (H29R; flow through) and mutated (H29C; retained) factor H proteins purified from patient HUS29, using anti-HSA affinity chromatography. Samples were not reduced. A silver-stained 10% polyacrylamide gel is shown.
