Abstract excerpt
Glioma cells with the isocitrate dehydrogenase (IDH) 1 G395A mutation are strongly immunopositive for mIDH1(R132H), an antibody against mutant IDH1(R132H) (clone H09). However, we encountered some gliomas which were ambiguously positive for mIDH1(R132H) despite having the IDH1 G395A mutation. The aim of this study was to establish an evaluation procedure of IDH1 status by immunohistochemistry. Forty-three...
