Applied Biosystems/MDS Analytical Technologies Advance Proteomics Research Through Suite of Integrated Mass Spectrometry Solutions
Applied Biosystems (NYSE:ABI), an Applera Corporation business, and its
joint-venture partner, MDS Analytical Technologies, a business unit of
MDS Inc. (NYSE:MDZ) (TSX:MDS), today announced the availability of a
suite of integrated mass spectrometry-based solutions for conducting
targeted quantitative proteomics studies. Designed for Applied
Biosystems/MDS Analytical Technologies’
industry-leading triple quadrupole and hybrid triple quadrupole/linear
ion trap mass spectrometry systems, these solutions include software
packages and consumables that enable scientists to more effectively
quantify proteins in biomarker research or cell biology.
These new tools address the needs of scientists in industry and academia
who are seeking to quantify many specific proteins and peptides in
complex biological samples. Thousands of proteins may be present in any
specific laboratory sample; however, scientists are often most eager to
study the subset of those that are typically lower in abundance and are
changing in response to a disease. Targeted mass spectrometry is
emerging as a powerful tool for these quantitative assays, yet key
challenges remain. The need for higher order multiplexing, improved
reproducibility and more rapid assay development for these protein
panels is critical for scientists to continue to drive forward their
biomarker initiatives in a streamlined, efficient manner. Applied
Biosystems/MDS Analytical Technologies’
targeted quantitative proteomics solutions are uniquely positioned to
address these challenges because they are designed to deliver
consistency along with simplified, one-touch accessibility to
world-class technology across the entire workflow. These new tools
include:
mTRAQ™ reagents are chemical labeling
kits for use in targeted proteomics experiments using MRM analysis
that can be used to create global internal standards to provide an
internal reference for every protein, peptide and post-translational
modifications in a sample, in a simple one-hour step. Based on
proprietary Applied Biosystems technology, mTRAQ reagents are designed
to improve analytical reproducibility for quantitative experiments
without the need for costly custom synthetic peptides.
Scheduled Multiple Reaction Monitoring is a
feature that focuses instrument cycle scans for specific analytes
based on the timeframe that those analytes will be entering the
instrument. In proteomics, this means the instrument can scan up to 10
times more peptides with better analytical precision and yielding more
information about each one. The Scheduled MRM™
Algorithm is part of Applied Biosystems/MDS Analytical Technologies’
updated operating system, Analyst®
1.5 Software, which powers its mass spectrometry systems.
MRMPilot™ Software is a new software
program for use with Applied Biosystems/MDS Analytical Technologies
QTRAP® Systems that
enable rapid development of robust MRM assays for peptides and
proteins utilizing data acquired during discovery experiments.
MRMPilot Software automatically builds MRM assays and utilizes
the unique MIDAS™ Workflow of the QTRAP
system for more seamless and far more efficient transition from
discovery to validation. These assays complement existing
widely used antibody-based assays, while requiring up to ten-fold less
time to develop and eliminating the need for purified proteins.
MultiQuant™ Software is a new
software package for use with Applied Biosystems/MDS Analytical
Technologies mass spectrometers that processes MRM data for
quantitative information. The software enables the efficient
processing of many analytes and samples at the same time, with an
emphasis on the requirements for processing protein/peptide
quantitative workflows.
New Approach to Mapping Proteomes at the Institute of Molecular
Systems Biology
An example of research enabled by these new tools is being performed by
Dr. Bruno Domon, a research scientist at the Institute of Molecular
Systems Biology in Zurich, Switzerland. Dr. Domon’s
laboratory has developed a workflow to perform proteomics assays that
was previously thought impossible due to constraints in the number of
peptides that could be measured by the mass spectrometer in a targeted
approach. His team is applying this workflow to biomarker studies on
samples in several disease areas with an emphasis in cancer and
diabetes. An initial step is to compile a set of putative biomarkers
from genomics or proteomics studies or published research, and then to
create Scheduled MRM Algorithm-based assays to quantitate the
proteins, thus bridging the span from discovery to validation. His work
has been enabled by early access to mTRAQ reagents in combination with a
4000 QTRAP LC/MS/MS system. The QTRAP System is a premier hybrid triple
quadrupole/linear ion trap mass spectrometer that delivers quantitative
and qualitative data within a single experiment.
Dr. Domon’s team attempts to map entire
proteomes. Beyond a simple cataloging of the proteins present in a
sample, they seek to measure and understand multiple forms of each
protein and what the changes that occur in the levels of these proteins
may signify. They have already completed the yeast proteome and are
currently working on others including drosophila. In both their
biomarker and mapping studies, the Scheduled MRM Algorithm-based
workflow has allowed them to measure proteins at much lower levels than
could be done with their previous approach, providing the ability to
scan a catalog of several hundred proteins in the course of an hour.
"Our laboratory has proposed a full paradigm
shift in how proteomics mass spectrometry experiments are done, from a ‘shotgun’
approach that was very effective in the early days of proteomics, to a
targeted, hypothesis-driven approach,” said
Dr. Domon. "Proteome studies are incredibly
complex. This method opens new opportunities to get deeper into
proteomes and get more comprehensive data sets, and it enables us to
potentially complete in a few days what would normally require several
months.” Improved Understanding of Virus Propagation at Yale University
Christopher Colangelo, Ph.D., director of mass spectrometry protein
studies at Yale University, is also conducting research aimed at finding
and verifying biomarkers for neurological diseases including autism,
schizophrenia and addiction. By reducing the statistical error and
generating higher confidence data through a workflow that consists of Scheduled
MRM Algorithm, mTRAQ reagents and iTRAQ®
reagents, and 4000 QTRAP system, his laboratory has been able to
reproducibly detect small changes in biomarker levels of 30 percent or
less.
Dr. Colangelo is also working with Drs. Megan Shaw and Peter Palese at
Mount Sinai School of Medicine as part of the Northeast Biodefense
Center to study how influenza virus interacts with the host cell
machinery during the viral life cycle. Their research has shown that
numerous host cell proteins are incorporated into the virus particle
along with the virus-encoded proteins. He has used MRMPilot and
Scheduled MRM to quantitate all nine influenza virus proteins and 32
host proteins found within the virus particle in a single experiment. In
one 75-minute experiment using sMRM, he was able to generate results
that originally took approximately 8 hours to perform.
"For our virus studies, our collaborators
want to know the precise concentration of each of these host proteins,
because if we begin to understand the role that these host proteins play
in the virus life cycle, it may create new opportunities for the design
of anti-influenza virus therapies to halt virus replication,”
said Dr. Colangelo. "For both the biomarker
and virus studies, the scheduled MRM workflow allows us to generate much
more information in each experiment, with much lower costs, and improved
sensitivity.”
