The Role of Tyrosine Kinases in Cancer and Drug Research

Luminex
28 Sept 2014

This white paper describes how Luminex xMAP Technology has been used to develop multiplex assays to advance the understanding of tyrosine kinase activity in several types of cancer, including glioblastoma, thyroid cancer, pediatric cancer, and lung cancer. It also covers novel ways that multiplex technology is being used in the study of tyrosine kinase related cancer drug therapy, through genetic testing of somatic mutations in the study of TKI response, and through the development of tyrosine kinase activity screens for drug discovery.

Luminex® 200™Multiplexing Instrument

Luminex

The Luminex® 200™ detects up to 100 protein or nucleic acid analytes from a single aliquot of sample in a single reaction well, enabling you to generate more data while saving sample, time, and reagents. With more than 11,000 units sold globally to date, the Luminex 100/200 is the established standard in multiplexing instrumentation. The xMAP® multiplexing platform is composed of an instrument and associated reagents: The Luminex 200 instrument is based on the principles of flow cytometry, which integrates key xMAP detection components such as lasers, optics, fluidics, and high-speed digital signal processors. xMAP microspheres are a family of fluorescently dyed carboxylated polystyrene microspheres that act as both the surface for the solution phase assay and the spectral identifier that the instrument detects. The open architecture of xMAP Technology enables users to build custom multiplex assays or select from a broad menu commercially available kits. Instrument Details: Multiplex Capacity: Up to 100 non-magnetic; 80 magnetic Microtiter Plate: 96 well Throughput: ~40 min/96-well plate (up to 12,800 tests per hour) Dynamic Range: 3.5 logs Sensitivity: Detects a minimum of 1,000 fluorochromes of phycoerythrin (PE) per xMAP microsphere Optics: Lasers/APDs/PMTs Hardware: Flow Cytometry based Software: xPONENT® Software supports protocol-based data acquisition with robust data regression analysis Dimensions: All components combined (Analyzer, XY Platform and Sheath Delivery System) 26.5" W x 23.5" D x 12.5" H (67.3 cm W x 59.7 cm D x 31.8 cm H) Weight: All components combined (Analyzer, XY Platform and Sheath Delivery System) 113 lbs (49 kg) xMAP Reagent Compatibility: Magnetic and nonmagnetic microspheres

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.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.BiomarkersBiomarkers are biological markers which can be measured and evaluated to indicate a biological state. The use of biomarkers in research and diagnosis can indicate a normal or disease state or drug response of cells / tissues. Biomarkers include genetic markers, cell surface markers such as antigens, antibodies or receptors and secreted molecules such as cytokines. An assay system is required for identification of biomarkers. :Cancer ResearchAlthough cancer is often referred to as a single condition, it actually consists of more than 100 different diseases. Microscopy, mass spectrometry, high throughput sequencing and flow cytometry are some of the most common techniques employed in cancer research labs.Biomarker DiscoveryClinical biomarkers refer to substances related to known medical conditions that can be accurately measured <i>in vitro</i>. Biomarkers can be used to diagnose presence of a disease and indicate disease severity. The discovery of new biomarkers is incredibly valuable in the field of diagnostics.Kinase Assays
