HercepTest™ is a semi-quantitative immunohistochemical assay for determination of HER2 protein (c-erbB-2 oncoprotein) overexpression in breast cancer tissues routinely processed for histological evaluation and formalin-fixed, paraffin-embedded cancer tissue from patients with adenocarcinoma of the stomach, including the gastroesophageal junction. HercepTest™ with the indication adenocarcinoma of the stomach, including the gastroesophageal junction, is not available on selected markets. HercepTest™ specifically demonstrates overexpression of HER2 protein. HercepTest™ is indicated as an aid in the assessment of patients for whom Herceptin™ (trastuzumab) treatment is being considered.

The kit includes reagents required for the immunohistochemical staining (except wash buffer), control slides representing different expression levels of HER2 protein, and detailed instructions. SK001 has been tailored especially for use on the Autostainer Link instruments.
