Figure 1. Quantitative TaqMan RT-PCR comparing expression of IL-13RA2 in canine primary brain tumors.

Elevated expression, relative to normal canine brain cortex, is seen predominantly in high grade glial tumors, essentially mirroring protein expression determined by western blotting. Off scale values are marked with an asterisk and value. MEN – meningioma; AST – astrocytoma; GBM – glioblastoma multiforme; OLIGO – oligodendroglioma.
