From: Heterogeneity of O6-alkylguanine DNA-alkyltransferase expression in human breast tumours
Photomicrographs of IHC staining for ATase in different breast tumours from the same patient (× 200). (A) High ATase staining (3+) in normal breast; (B) no staining (−) in primary breast tumour; (C) variable staining in a metastatically infiltrated axillary lymph node. Also shows capsular infiltration by tumour.
