Fig. 6. Stable clones expressing CaD39-AB. Total proteins were prepared from five independent stable cell lines (C35, C42, m4-2, m5-8 and m4-65) and a non-expressing cell line C3. Equivalent amounts of protein extract were resolved using SDS-PAGE and the portion of the Coomassie-Blue-stained gel was shown (B) to indicate the equal loading in the gel. The expression levels of CaD39-AB in the stable clones were analysed by western blot (A).
