Comparison of PTB and Notch1IC staining intensities in paired serial cores. (a) The graph shows PTB and Notch1IC staining intensity for 423 paired tissue cores. (b) Staining intensity data from the subset of 114 serial cores derived from patients with grade IV glioblastoma. The numeric values for PTB and Notch1IC staining intensities were determined from the scanning analysis (see Materials and methods). Samples are ordered by increasing PTB staining intensity independent of tumor grade.
