Affymetrix Launches Updated Whole-Genome Drosophila Array for Gene Expression
Analysis
Array Design Based on Berkeley Drosophila Genome Project Database Release 3.1
SANTA CLARA, Calif., March 17 /PRNewswire-FirstCall/ -- Affymetrix, Inc.,
today announced that it is taking orders for its new GeneChip(R) Drosophila
Genome 2.0 array, offering researchers the most comprehensive and up-to-date
microarray available for Drosophila melanogaster gene expression research.

The design of the new array was largely based onthe content from the recent
annotation (release 3.1) of the Drosophila melanogaster genome by Flybase and
the Berkeley Drosophila Genome Project (BDGP), funded by the National Human
Genome Research Institute, Department of Energy, and the Howard HughesMedical
Institute. In addition, other published gene predictions from the Drosophila
Research community were also included.
Gerald Rubin, Ph.D., Director of the BDGP commented on the recent Drosophila
genome release: "The Drosophila community contributed new data, computational
analysis, and human curation to create Release 3.1, a significant improvement on
our view of the genome which the previous generation Drosophila Affymetrix array
was based."
"This array is not only based on the most recentview of the genome, it also
utilizes our sophisticated probe selection methods and leverages our
high-resolution platform for improved analysis," said Lianne McLean, Director,
Gene Expression Marketing, Affymetrix. "The new array design includes over 30%
more content than the previous generation Drosophila melanogaster design. Our
customers are excited about this release." Affymetrix' probe set strategy,
which uses multiple data points to measure each transcript, has been proven
through a series ofrigorous and exacting performance benchmarks to provide an
unparalleled level of data quality. In total, the array uses over 500,000 data
points to measure the expression of 18,500 transcripts and variants.
Twenty-eight different probes are used to measure each individual transcript,
providing optimal sensitivity and specificity, and the most accurate,
reproducible and statistically significant results possible.
Affymetrix has become the industry standard technology for gene expression
analysis, with over 2,000 papers in total published using the GeneChip
technology.
The Drosophila Genome 2.0 Array is part of Affymetrix' latest generation system,
which includes new instruments, reagents and higher density arrays. The new
arrays offer over two and a half times more data on a single array, putting high
quality, affordable whole-genome analysis within the reach of individual
researchers worldwide.
Affymetrix will provide quarterly updates of Drosophila sequence and annotation
information through NetAffx(TM) Analysis Center to keep researchers abreast of
the latest annotation developments. Affymetrix launched its first Drosophila
melanogaster array in 2000.
