Association of CD2AP and nephrin in podocyte cell line. A: Insolubility of nephrin and CD2AP from purified glomeruli. Glomeruli were purified from mouse kidneys by sieving. Lysates were prepared with digitonin based lysis buffer. A portion of the soluble material (S) and a portion of the insoluble material (I) was analyzed by SDS-PAGE and immunoblotting with antibodies to CD2AP and nephrin. B: Lysate were prepared from a podocyte cell line. Equal amounts of the clarified lysate were incubated with either pre-immune rabbit serum (C) or affinity purified CD2AP antibody (CD2AP). Immunoprecipitates were analyzed by SDS-PAGE and immunoblotting with anti-nephrin. Either whole cell lysate (-) or anti-nephrin immunoprecipitate (Nep) were loaded as positive controls.
