Breast cancer IHC/ISH portfolio

Deliver diagnostic confidence with the Roche breast cancer IHC portfolio

A leader in breast cancer diagnostics, Roche Diagnostics offers numerous cancer diagnostic assays that enable pathology labs to deliver accurate results with confidence. We provide a robust menu of breast cancer diagnostic tools. Our portfolio of products delivers the high sensitivity and specificity you need from your assays.

 

Immunohistochemistry (IHC) analysis and in situ hybridization (ISH) analysis

Experts predict over 500,000 deaths annually due to breast cancer, making it a leading cause of death in women. In developed countries breast cancer related mortality has declined, in part due to therapeutic advances and evolution of biomarkers. For example, Immunohistochemistry (IHC) analysis and in situ hybridization (ISH) analysis provide important information related to tumor biology, help profile types of breast cancer and may improve treatment decisions.

 

Clinical benefit

With proven accuracy, VENTANA breast cancer diagnostic assays help you identify patients other assays can miss – so you can deliver the right test, with clinical confidence in the shortest possible time.

 

Analytical advantage

Specific and sensitive rabbit monoclonal antibodies, best-in-class probes, and powerful detection systems help you diagnose precisely and confidently.

 

Testing efficiency

Our comprehensive breast cancer workflow solution delivers fully-automated assays on market-leading platforms, with digital pathology and workflow solutions that free resources, reduce labor costs, and reduce time to results.

Featured Assays

HER2 4B5
PATHWAY HER2 (4B5) Rabbit Monoclonal Primary Antibody

The use of pre-diluted PATHWAY HER2 (4B5),14 in combination with the fully automated VENTANA BenchMark IHC/ISH slide staining instrument, standardizes all IHC processes from baking through staining, and reduces the possibility of human error. It also minimized inherent variability resulting from individual reagent dilution and other processes found in manual and semi-automated IHC methods. 

The PATHWAY HER2 (4B5) Primary Antibody empowers you to: 
  • Achieve consistently high proficiency assessment scores with HER2 (4B5) antibody, compared to other clones15
  • Employ the most widely adopted and reliable HER2-IHC primary antibody15
  • Demonstrate high concordance with HER2 FISH16,17
HER2
INFORM HER2 Dual ISH DNA Probe Cocktail assay
  • FDA-approved as an aid in the assessment of patients for whom Herceptin (trastuzumab) treatment is being considered.
  • Convenient brightfield detection technology to perform a comprehensive analysis of tissue on the slide, and evaluate HER2 gene status with morphological context
  • Identify intratumoral heterogeneity
  • Greatly reduced time to result with full automation1,2
  • Run the test in-house instead of sending it out
SP1
CONFIRM ER (SP1) Rabbit Monoclonal Primary Antibody
  • FDA cleared antibody
  • Indicated as an aid in patient management, prognosis, and the prediction of therapy outcomes in breast cancer.6
  • ER (SP1) is a significant predictor of disease-specific survival.7,8
  • Rapid and consistent results delivered through fully automated platforms and digital pathology solutions
PR
CONFIRM PR (1E2) Rabbit Monoclonal Primary Antibody
  • FDA cleared antibody
  • Indicated as an aid in patient management, prognosis, and the prediction of therapy outcomes in breast cancer.9
  • Provide significant value as a prognostic factor and response prediction of hormone therapy, even in ER negative patients.10
  • Rapid and consistent results through fully automated platforms and digital pathology solutions
KI-67
CONFIRM anti-Ki-67 (30-9) Rabbit Monoclonal Primary Antibody
  • Aids in assessing the proliferative activity of normal and neoplastic cells
  • Rabbit monoclonal antibody demonstrates increased sensitivity and strong specificity compared with mouse monoclonal antibodies
  • Intense nuclear staining and no adipose (K2) or cell membrane staining can help deliver a confident assessment of tumor aggressiveness
