SBK3 and SBK4 peptide probes specifically recognize human glioblastoma tissue but not normal brain. Sections of noncancerous normal cortical brain tissue from epilepsy patients or GBM tumor were histochemically labeled with TR-conjugated SBK3, SBK4, or scrambled SBK2 peptides. Two examples of normal and GBM tissue are shown, which are representative of six different samples examined.
