Product news

Thermo Fisher Scientific Inc. today announced its new Thermo Scientific QMS Everolimus Reagent kit, the newest assay in the group of immunosuppressant drug monitoring products. The QMS® Everolimus Reagent kit, which rounds out the company's full array of immunosuppressant immunoassays that includes Cyclosporine, Tacrolimus and Mycophenolic Acid, was the first to receive U.S. Food and Drug Administration clearance for monitoring the appropriate blood levels of everolimus, a drug that helps prevent rejection in kidney transplant patients.

The company will showcase the products at Thermo Scientific booth #1720 during Clinical Lab Expo at AACC 2011, being held July 26 – July 28, at the Georgia World Congress Center, Atlanta, Georgia.

Thermo Scientific products have a proven track record for supplying high-quality reagents, calibrators and controls since 1989. Thermo Fisher's homogeneous immunoassay products have been used in many major clinical laboratories and drug testing facilities around the world. The newest, ready-to-use liquid QMS Everolimus assay is used as part of therapeutic drug monitoring, an integral part in organ transplant recipient treatment programs. Based on the Thermo Scientific Quantitative Microsphere Systems (QMS), a homogeneous particle-enhanced turbidimetric technology, the Thermo Scientific QMS Everolimus assay is used on automated clinical chemistry analyzers for quantitative determination of everolimus in human whole blood, the active ingredient in the Novartis immunosuppressant drug - trade name Zortress®.

Strategies for immunosuppressive treatment have focused on preventing T lymphocyte cell activation and/or proliferation. Everolimus acts as a proliferation inhibitor. Thermo Scientific QMS Everolimus Calibrator and Control sets are also available for use with the QMS Everolimus Assay. The calibrator kit contains six different calibrators to complete a full six-point calibration, as part of the test procedure; and the QMS Everolimus Control Set contains three levels.

As manufacturers continue to develop new drugs, monitoring the therapeutic ranges for each drug becomes more important. Transplant physicians working with clinical laboratories, for example, must carefully manage dosages to avoid organ rejection caused by low levels of the immunosuppressant drugs or toxicity issues caused by excessive levels of a drug or a potentially lethal combination. Fortunately, Thermo Fisher is constantly innovating, delivering new assay methods, calibrators and controls that build on its history of product reliability, accuracy, ease-of-use and lot-to-lot consistency.

Combinatorial ChemistryCombinatorial chemistry, also known as combichem, is a technique used in drug discovery to create libraries of structurally related compounds. A library is generated by synthesis with a chemical reactor system or by computer-based modeling of compound combinations. When undertaking combinatorial chemistry consider reagents, buffers, resins and standards.Cell Lines Stem Cells and Primary CellsPrimary cell cultures, established cell lines and stem cells are vital for <i>in vitro</i> and <i>ex vivo</i> experimentation. High-quality cells, optimized for your applications, alongside optimized cell substrates, growth medium and supplements, are critical for experimental success. Explore a range of cells suitable for your applications, including isogenic cell lines, competent cells, induced pluripotent stem cell (iPSC)-derived cell lines, fungal/bacterial/mammalian cell lines, stem cells and cancer cell lines. Find the best cells for your research in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Assay AssemblyAssay Assembly is technique used in drug discovery to develop assays to test the cytotoxicity, genotoxicity, or other activities of a compound on a cell. Assay assembly requires chip assembly, a delivery system and a detection and analysis method. Beneficial features of assay kits or automated systems include high-throughput, high speed and sensitivity and low signal to noise ratio.Medicinal ChemistryMedicinal chemistry is a broad discipline encompassing the design, identification, synthesis and development of chemicals in drug discovery. It includes a number of techniques covering structural biology, synthetic chemistry and molecular biology. Technologies used in medicinal chemistry include ADME, lab-on-a-chip, high content screening and assay assembly.Process ChemistryProcess chemistry is an important stage of drug development for scaling-up drug production or chemical synthesis reactions. It is useful for optimizing economical and efficient drug production. Process chemistry uses reactors and pump systems as well as reagents, standards and buffers.HematologyIn Haematology / Hematology, complete blood cell counts (or full blood counts) are obtained using automated blood count analyzers to enumerate blood cell types.  Hematology also encompasses haemostasis and coagulation, thrombophilia and hemophilia, plasma viscosity and ESR analysis, hemoglobinopathies, cell morphology and haematinic measurement.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.Cell-Based AssaysCell-based assays are used to monitor the presence, quantity and activities of a desired cellular analyte including drug molecules or biomarkers. This can reveal information on cell health (apoptosis, cytotoxicity, viability and proliferation assays), cell metabolism, cell migration and cell signaling mechanisms. Find the best cell-based assay products, kits and equipment with our peer reviewed product directory: compare products, check customer reviews and receiving pricing direct from manufacturers.High-Content ScreeningHigh-content screening (HCS), also known as high-content analysis (HCA), is a high-throughput technique used in drug discovery to identify substances that alter the phenotype of cells. HCS uses fluorescent microscopic imaging and automated image analysis to investigate cellular events such as apoptosis, cell viability, GPCR activation, oxide production, neurite outgrowth, and cell signaling. Find the best fluorescent labeling reagents, cellular assays, and high-content imaging systems in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Clinical TrialsClinical Trials, an essential part of drug discovery process, assess the safety and effectiveness of a new medication or device in the pharmaceutical industry. Clinical Trials are a phased process (Phase 0, Phase I, Phase II, Phase III and Phase IV) which begins after initial preclinical testing.
