Pyrosequencing AB:s Patented DNA Sequencing Technology to Assist the National Institutes of Health in Identifying Type 2

Pyrosequencing AB's Patented DNA Sequencing Technology to Assist the National Institutes of Health in Identifying Type 2 Diabetes Gene --Company receives two orders for PSQ@ 96 system-- Uppsala, Sweden, September 11, 2000- Pyrosequencing AB (SSE:PYRO), a devel- oper, manufacturer and marketer of complete systems for applied genetic analy- sis, today reported that the National Institutes of Health's (NIH) National Institute of Diabetes & Digestive & Kidney Diseases (NIDDK) has ordered two of the Company's sequencing systems, the PSQ@ 96. The NIDDK will use the Com- pany's Pyrosequencing@ technology to study the relationship between varia- tions, or Single Nucleotide Polymorphisims (SNPs), in genes of diverse patient populations suffering from Type 2 diabetes. "In studies involving Pima Indians, we have identified a region on chromosome 1 that is linked to Type 2 diabetes mellitus. This same genetic region was im- plicated in Type 2 diabetes susceptibility in the Old Order Amish and in Cau- casians living in Utah. Therefore, genes in this region may play an important role in the development of Type 2 diabetes," explained Johanna Wolford, Ph.D., a scientist at the NIH. "It is our hope that we can rapidly sequence the SNPs and candidate genes in this region, and identify genetic mutations associated with Type 2 diabetes." Pyrosequencing's PSQ 96 provides rapid SNP sequencing, and is the first com- mercially available dedicated sequencing-based system for applied genetic analysis. Based on the Company's patented Pyrosequencing@ technology, the product provides rapid and accurate genetic analysis and offers a high capac- ity, cost-effective solution for SNP analysis and Tag sequencing- the analysis of short DNA sequences used for genetic identification. PSQ 96 Systems, launched earlier this year, include a sequencing instrument, software, and reagent kits necessary to conduct SNP analysis. "We are excited that the NIDDK has selected our technology to carry out this important work," said Erik Walldén, President and CEO of Pyrosequencing AB. "There are several technologies available to perform SNP analysis, and we are gratified that the PSQ 96 System was judged as the one that has the best in- ternal quality control, automated processing capabilities, as well as the most user-friendly system for applied genetic analysis." The NIDDK conducts and supports research on many of the most serious diseases affecting public health. The Institute supports much of the clinical research on the diseases of internal medicine and related subspecialty fields as well as many basic science disciplines. The Institute supports basic and clinical research through investigator-initiated grants, program projects and center grants and career development training awards. The Institute also supports re- search and development projects and large-scale clinical trials through con- tracts.
