NEFL and glioblastoma: Interestingly, in all cases, BIOT-NFL (visualized in green) was attached on GBM cells, and an amount of peptide was every so often detected near the nucleus even at this low concentration of peptide, as seen in Fig. 7E. Here, only confocal images showing the peptide were presented, as at this low concentration of BIOT-NFL (0.3 μM), the peptide was not found in all scenes.
