Figure 2: GSCT selectively binds Nestin-positive tumor cells in human GBM tissues. Paraffin-embedded human GBM tissue sections were stained with a biotinylated-GSCT (B-GSCT) peptide (Green) and Nestin antibody (Red). This immunofluorescence analysis revealed that most B-GSCT peptide-targeting tumor cells are colocalized with Nestin-positive tumor cells [27]. With reprint permission from Elsevier.
