Abstract
With a previous NIH NHGRI grant ("Capillary Automated Submicroliter
Sample Preparation", 5/97 - 4/01, $2,637,490 direct) I have developed
an automated fluid sample handling system called "Acapella." This
instrument, developed with Orca Photonic Systems, Inc. (subcontractor),
prepares small (1 to 2 microliter) reactions inside glass capillaries
for biological protocols such as PCR (Polymerase Chain Reaction to amplify
DNA), sequencing reactions, and restriction digests. The system is
a general purpose chemistry analysis system that is intended to
greatly reduce the costs, increase the throughput, and improve the
reliability of samples that are prepared. Our first application is
for large-scale DNA sequencing. Our goal is to decrease costs by
10 times, and to produce 5000 samples in 8 hours. One of our instruments
will be able to support any where from 3 to 10 of the modern capillary
electrophoresis sequencing instruments.
In this new advanced development grant we have been funded to develop
new automated modules for the ACAPELLA system. These include automated
thermal cycling, purification, and loading to the sequencing instruments.
A big part of the project is to extensively test the instrument with the
users for large-scale DNA sequencing. We have a series of alpha tests
lined up with the UW Genome Center (Maynard Olson). Then we will run
a series of beta tests with 3 centers: UW Genome Center, Washington
University St. Louis Genome Sequencing Center, and the Whitehead
Institute/MIT Center for Genome Research. The St. Louis and Whitehead
centers are very large-scale production centers for DNA sequencing and
will provide a serious test for the instrument.
Technology associated with this project will be disseminated and
commercialized to bring the ACAPELLA systems to the point where
they can be deployed to major genome centers and for other applications.
Automated Minimal Residual Disease Quantification
NIH National Cancer Institute
June 1, 2000 - May 31, 2004
Award amount:
|
$2,170,590

Subcontracts:
|
Orca Photonic Systems Inc., Redmond, Washington

Other UW investigator:

Prof. Daniel Sabath, Dept. Laboratory Medicine

Abstract
In this project an automated system is being developed to quantify
minimal residual disease (MRD) by using real-time PCR (Polymerase
Chain Reaction) to quanfity cancer cells in a background of
non-pathologic DNA. The system will derive some technology from
the Acapella system (described above). A real-time thermal cycler
will be developed that will provide DNA quantification results
with greater precision than what is currently possible with commercial
instruments by taking advantage of a high performance custom
fluorescence analyzer and sophisticated data analysis methods.
Performance of the system developed will be evaluated on real
biological samples provided by the UW Department of Laboratory
Medicine.Results returned by the system will be compared with
results of PCR experiments performed in Laboratory Medicine run
on a commercial instrument for the diagnosis of patients suffering
from follicular lymphomas.
