Affymetrix launches microarray-based analysis system for
cytogenetics
8 April 2009
Affymetrix, Inc. (Nasdaq: AFFX) has launched its next-generation
series of products for cytogenetics. The new system, which includes
arrays, reagents, and software, enables fast and reliable detection of
known and novel chromosome aberrations.
“We worked closely with the cytogenetics community to develop these
products,” said Jay Kaufman, vice president of product marketing at
Affymetrix. “We identified critical and high-demand features specific to
cytogenetics studies, and leveraged our proven microarray platform to
develop products that delivered those features. Then, we streamlined and
simplified workflows and protocols from sample preparation to data
analysis to help ensure success of all users—both those who have prior
microarray experience and those who are new to the technology.”
The next-generation Affymetrix Cytogenetics system brings
comprehensive microarray-based genetic analysis capabilities to a
broader range of scientists than ever before, delivering high-value,
customer-focused benefits, including confidence, simplicity, and
flexibility.
The new system delivers consistently high performance for discovery
and detection of chromosome aberrations, so users can be highly
confident in the results. With development guided by cytogeneticists,
the products are targeted to the specific needs of users.
The Affymetrix Cytogenetics Whole-Genome 2.7M Array and Cytogenetics
Focused Array include copy number (CN) and single nucleotide
polymorphism (SNP) content to identify loss of heterozygosity (LOH),
uniparental disomy (UPD), and regions identical-by-descent.
With the Whole-Genome 2.7M Array, users can detect the broadest range
of known and novel chromosome aberrations that affect phenotype. The
array provides unbiased, whole-genome coverage with 2.7 million markers,
including 400,000 SNPs, to offer superior resolution and enable
detection of even the smallest structural changes and regions of
autozygosity.
The Focused Array includes more than 330,000 markers to enable
efficient detection of aberrations within focused regions of known
cytogenetic importance. At the same time, it maintains a backbone of
markers at 16 kb spacing to provide whole-genome coverage. Both arrays
offer dense coverage of cytogenetic hot spots, including
haploinsufficiency genes, cancer genes, and regions associated with
microdeletion syndromes.
The new Affymetrix Cytogenetics Assay has been simplified and
streamlined. Tedious polymerase chain reaction (PCR) steps and
restriction digests have been eliminated to save users time and money,
reduce operator error, and deliver reliable results from one run to the
next. In fact, the entire assay requires only three hours of hands-on
time.
“We are confident that our next-generation solution offers
cytogenetists the best overall approach for discovery and detection of
chromosome aberrations,” said Frank Witney, chief commercial officer at
Affymetrix. “No other set of commercial catalog products offers the
combination of high-resolution, cytogenetics-specific, and whole-genome
CN and SNP content, a streamlined and simplified assay protocol, and
software that offers almost unlimited options for data visualization,
analysis, and reporting.”
