DOE Solicits Applications for Genome Instrumentation Research
In April the DOE Office of Biological and Environmental Research (BER) announced its interest in receiving new applications in genome instrumentation for both substantial evolutionary improvements in current systems and revolutionary technologies for the post-2005 era (see box). BER especially wishes to stimulate contributions from investigators not previously involved in the Human Genome Program and invites applications from a broad range of scientists with backgrounds in biology, chemistry, physics, and engineering.The solicitation was the topic of an editorial in the May 1 issue of Analytical Chemistry [70(9), 292A], in which Royce Murray (University of North Carolina, Chapel Hill) urged readers to think creatively about the role analytical chemists might play in fulfilling OBER goals.
DOE's transition to production sequencing has been based largely on gel electrophoresis, with data acquisition by laser-induced fluorescence. However, this in no way decreases the necessity for innovative long-term basic research in the area of instrumentation in support of genome studies. In this context, BER is refocusing its current Genome Instrumentation Program, taking stock of current progress and thoughtfully considering the future.
To complete the human genome within the available budget and time, substantial improvements in existing sequencing methods would be advantageous. Further, BER places a strong emphasis on research directed to completely new approaches to genomic analysis. After 2005 the ongoing need will be for fast and cost-effective determination of DNA sequence to compare sequences among human individuals and also to determine the genomes of numerous organisms of biomedical and commercial interest. Additionally, with the continuing acquisition of this remarkable base of biological data, high-throughput experimental tools will be required to assist in a practical and useful understanding of gene function.
Specific items in the solicitation notice include:
- Approaches to determining DNA sequence more rapidly, accurately, and economically, particularly to increase current maximum read lengths at least 2.5 times, to 2000 to 2500 bases.
- Instrumentation that integrates and more thoroughly automates DNA sequence determination (e.g., sample preparation, loading, and analysis) and data analysis. Priority will be placed on approaches that emphasize miniaturization and microfabrication.
- Approaches that (1) verify a previously determined DNA sequence's accuracy without having to redetermine its entire sequence and (2) provide economical error-checking and proofreading of newly determined DNA sequence.
- Tools that enable efficient comparison of a known DNA sequence with a related but previously undetermined DNA sequence.
- Techniques for determining the functions of large numbers of genes in parallel, particularly those that match the speed and volume of DNA sequence determination.
Preapplications due: June 8 (Preapplications are recommended but not required. Potential applicants should contact OBER program staff.) Applications due: August 19 CONTACT: Charles G. Edmonds (301/903-0042, Fax: -0567, charles.edmonds@oer.doe.gov) |
