Fig. 1: The extract of A549 (40ug) were resolved by SDS-PAGE, transferred to PVDF membrane and probed with anti-human BMP8b antibody (1:500). Proteins were visualized using a goat anti-mouse secondary antibody conjugated to HRP and an ECL detection system. Fig. 2: The Human Recombinant protein BMP8b (200, 100, 50ng) were resolved by SDS-PAGE, transferred to PVDF membrane and probed with anti-human BMP8bq antibody (1:1000). Proteins were visualized using a goat anti-mouse secondary antibody conjugated to HRP and an ECL detection system.
