Leica Biosystems, a division of Leica Microsystems, has announced that it has received Pre-Market Approval from the U.S. Food and Drug Administration (FDA) for the Leica Bond Oracle HER2 IHC System with the Leica BOND-MAX. The Leica Bond Oracle HER2 IHC System is a complete solution of ready-to-use reagents, HER2 control slides and Leica BOND-MAX instrumentation, designed to deliver increased diagnostic confidence and drive laboratory efficiency in HER2 IHC testing.

“The Leica Bond Oracle HER2 IHC System demonstrates high concordance to HER2 FISH“, comments Arnd Kaldowski, President of Leica Biosystems. “The Leica Bond Oracle HER2 IHC System is validated as a fully-automated HER2 IHC test, and delivers the diagnostic confidence that comes with proven HER2 FISH concordance. With the Oracle system, laboratories also obtain the speed and efficiencies of Leica BOND-MAX instrumentation, delivering more effective workflow management”.

The Leica Bond Oracle HER2 IHC System is intended for use on formalin-fixed, paraffin-embedded tissue, and can be used simultaneously with all other BOND protocols allowing unparalleled flexibility and workflow efficiency.
In clinical trials the Leica Bond Oracle HER2 IHC System achieved 2x2 concordance of 87.6% and a positive agreement of 93.8% with the Abbott Molecular PathVysion HER2 DNA Probe kit, considered the gold standard for assessment of HER2 status.

Full automation of HER2 IHC testing facilitates decreased process variation, increased protocol standardization and the delivery of consistent results. Confidence is further enhanced by the use of HER2 Control Slides demonstrating 0, 1+, 2+ and 3+ staining. "Use of the 2+ (equivocal) cell line, has the potential to improve assay performance, as this is a sensitive indicator of problems associated with antigen retrieval, primary antibody, or detection system", says Dr. Anthony O'Grady, Beaumont Hospital, Ireland.

Leica Bond Oracle HER2 IHC System is a semi-quantitative immunohistochemical (IHC) assay to determine HER2 (Human Epidermal Growth Factor Receptor 2) oncoprotein status in breast cancer tissue processed for histological evaluation. The Leica Bond Oracle HER2 IHC System is indicated as an aid in the assessment of patients for whom Herceptin® (trastuzumab) treatment is being considered.

Genome AnalysisGenomics, the study of genomes, includes functional genomics, evolutionary genomics and comparative genomics. There are many genomic technologies such as DNA sequencing of whole genomes, computational biology and bioinformatics. DNA and nucleic acids must be isolated and concentrated from cells for analysis with kits, automated analyzers and software. Other useful technologies for studying genomics include PCR, microarrays and electrophoresis.Gel Doc / Image AnalysisGel documentation (gel doc) or gel imaging systems are used for the analysis of proteins, antibodies and nucleic acid immobilized in polyacrylamide or agarose gels, membranes or microarrays. Explore a range of a gel imaging systems, densitometers, scanners, transilluminators or UV lamp + CCD cameras for your image analysis solutions. Colorimetric, fluorescent and/or radioisotopic samples can be visualized and documented for further analysis. See gel doc / Image analysis software for quantitative 1D and 2D analysis of your samples. Find the best gel doc / image analysis products in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.ImmunologyImmunological techniques measure and characterize immune responses. Immunology kits and analysis systems often use techniques such as ELISA, radioimmunoassay (RIA) and immunodiffusion assays, Immunohistochemistry, and flow cytometry. Immunologists use equipment such as flow Cytometers, plate readers, plate washers and fluorescent microscopes.Cellular PathologyCellular Pathology deals with the microscopic analysis of tissue samples and cells. Sample preparation and processing includes fixation, staining, sectioning and slide mounting, using equipment such microtomes and cryostats. In choosing immunohistochemistry and immunocytochemistry kits, consider chromogens, staining method, antibodies, microscopes and imaging.HER2FDAThe Food and Drug Association (FDA) is an agency within the U.S. Department of Health and Human Services. Among other things, it is responsible for ensuring the safety, effectiveness and quality of drugs, vaccines and other biological products, and medical devices.
