Comparison of Western blotting patterns of anti-C15 and anti-C9. (A) Km3 lysate (20 μg/lane) was separated in 8% SDS-PAGE, transferred to nitrocellulose paper, and probed with anti-C15 (lane 1), anti-C15 plus anti-C9 (lane 2), and anti-C9 (lane 3). (B) K562 lysate (20 μg/lane) was separated in 4% SDS-PAGE, transferred to nitrocellulose paper, and probed with anti-C15 (lane 1) and anti-C9 (lane 2).
