Applied Biosystems/MDS Analytical Technologies to Demonstrate Productivity Solutions at International Mass Spectrometry Conference

Mass spectrometry, which was until recently a complicated technology available exclusively to highly trained experts, is today a workhorse analytical technique for a wide variety of scientific applications including basic research, drug discovery and development, food and environmental contamination testing and forensic analysis.

Mass spectrometry, which was until recently a complicated technology available exclusively to highly trained experts, is today a workhorse analytical technique for a wide variety of scientific applications including basic research, drug discovery and development, food and environmental contamination testing and forensic analysis.

The development of this powerful technology into an accessible platform for scientists across disciplines will be the focus for Applied Biosystems (NYSE:ABI), an Applera Corporation business, and its joint venture partner, MDS Analytical Technologies, a division of MDS Inc. (NYSE:MDZ)(TSX:MDS), during the 56th annual American Society of Mass Spectrometry (ASMS) conference in Denver, May 31-June 3. The ASMS conference draws scientists in a variety of fields from around the globe each year to present and learn about the newest developments in mass spectrometry. Throughout the conference, Applied Biosystems/MDS Analytical Technologies will showcase new integrated software applications, as well as methods and chemistry reagents that provide greater productivity through its world-class mass spectrometry-based solutions.

Applied Biosystems/MDS Analytical Technologies scientists and collaborators will deliver more than 70 presentations highlighting recent and ongoing research enabled by their technology platforms. These presentations will exemplify how newly released software applications and chemical reagents deliver complete, integrated workflows for applications ranging from the discovery, validation and verification of biomarkers to drug metabolism studies to the detection and measurement of environmental contaminants.

For example, Ethan Badman, Ph.D., a principal scientist at Hoffman-La Roche, Nutley, NJ, a leading global healthcare company headquartered in Basel, Switzerland, will discuss the theory behind matrix factors, a quantitative measure for matrix effects in biological samples. Applied Biosystems/MDS Analytical Technologies has developed a new, automated method for its instruments that allows a one-touch approach to determining the matrix factor. Matrix factors are now suggested to be calculated for mass spectrometry-based bioanalytical assays, according to the 3rd Crystal City Bioanalytical conference report.(1) Calculation of matrix factors provides a clear understanding of the matrix effects in bioanalytical assays.

"The procedure developed by Applied Biosystems essentially lets us open a template, click, and get the matrix factors we need," says Dr. Badman. "It is much easier because it is all automated, compared to calculating matrix factors manually. The fact that the algorithm is built-in reduces calculation errors."

Applied Biosystems/MDS Analytical Technologies will be hosting a variety of events as part of its program focused on complete productivity solutions, including a proteomics luncheon workshop on Monday. Christie Hunter, Ph.D., a senior staff scientist at Applied Biosystems, will review how the joint venture's integration of hardware, software, and reagents can be used to reproducibly quantitate hundreds of proteins for targeted proteomics applications, including biomarker studies. This extends the targeted proteomics approach, which is being called the fourth generation of proteomics by thought leaders.

Applied Biosystems/MDS Analytical Technologies will also host a workshop on Tuesday focused on the powerful combination of triple quadrupole and ion trap technology as a single platform. Applied Biosystems/MDS Analytical Technologies' QTRAP^® system is the only platform available that can seamlessly integrate quantitative and qualitative analysis in a single experiment. On Wednesday, there will be an additional workshop that will concentrate on the value of integrated services for validation and remote system monitoring for regulated laboratories. This workshop will provide an overview of the U.S. Food and Drug Administration's latest thinking and trends for laboratory compliance, and highlight the availability of an expanded suite of Smart Monitoring and Compliance services from Applied Biosystems Global Services. These include: Installation Qualification/Operation Qualification (IQ/OQ), Operation Qualification/Instrument

Performance Verification (OQ/IP), and Software Validation.
"The emphasis of the Applied Biosystems/MDS Analytical Technologies joint venture continues to be on developing complete workflows that enable scientists to take full advantage of the power of our systems, and maximize the amount of information they derive from each experiment," said Laura Lauman, president for Applied Biosystems' proteomics and small molecules division. "This delivers the ability to advance knowledge and understanding, whether it is helping pharmaceutical customers develop new and better medicines, those in academic research to continue to understand the complexities of biology, or helping testing agencies to ensure the safety of our food and water."

OTHER ASMS HIGHLIGHTS:
Applied Biosystems/MDS Analytical Technologies' expanded suite of powerful mass spectrometry software and solutions to increase scientific productivity will be on display in Booth #137 at the Denver Convention Center and at the Denver Sheraton Hotel in Grand Ballroom 1. These include:

• iMethod^TM Tests for Cliquid^® Software; These are downloadable methods announced earlier this year that enable users of Cliquid Software instant access to customizable turnkey solutions for routine food and beverage testing. The methodsdownload from an application microsite onto their PCs for easy upload directly into Cliquid Software.

• mTRAQ^TM Reagents; These are proprietary chemistry kits being introduced that provide a global reference standard for every protein in a simple one-step procedure for proteomics studies and enable reproducible biomarker verification and targeted quantitative proteomics.

• Analyst^® 1.5 Software; This is the updated operating system for Applied Biosystems/MDS Analytical Technologies' mass spectrometry systems, which incorporates new methods and workflows for increased productivity.

• Biocrates AbsoluteIDQ^TM Kits; These are reagent kits for targeted metabolomics studies to identify and quantify over 150 metabolites across four different metabolite classes from a small (10 microliter) plasma sample in only minutes per sample.
