Immunodetection of versican isoforms in human melanoma and astrocytoma cell lines. Western blot of conditioned media from human SK-mel-1.36-1-5, SK-mel-3.44, and SK-mel-23 human melanoma cell lines and U251 astrocytoma cells proved with the anti-GAG-β antibody (left) and the anti-GAG-α antibody (right). The arrow marks a proteolytic-derived form of versican.
