MET and glioblastoma: In addition, the biotin-conjugated goat anti-MET antibodies also induced the cluster formation of the phosphorylated MET receptor on the plasma membrane in other human glioblastoma cells such as T98G cells (Fig. S1B), suggesting the ability to induce the activation and cluster formation by the biotinylated anti-MET antibodies are not limited to U373-MG cells.
