Applied Biosystems Announces New Tools for Studying MicroRNAs.


TaqMan([R]) Arrays Enable Large-Scale Expression Profiling Microarray technology is often used for gene expression profiling. It makes use of the sequence resources created by the genome sequencing projects and other sequencing efforts to answer the question,  of Small RNAs

FOSTER CITY, Calif. -- Applied Biosystems Applied Biosystems, Inc. (formerly NASDAQ: ABIO) is the original name of a pioneer biotechnology company founded in 1981 in Foster City, California, among the Silicon Valley cities of the southern San Francisco Bay Area.  (NYSE NYSE

), an Applera Corporation business, today announced the release of the first TaqMan([R]) assays for microRNA (miRNA) analysis that are configured in an array format. The TaqMan([R]) Array Human MicroRNA Panel is a molecular tool that can help researchers in pharmaceutical companies and academic institutions more rapidly and efficiently search for miRNA biomarkers associated with disease and accelerate research related to how microRNAs impact biological processes. Using gold-standard TaqMan([R]) assay chemistry for quantitative gene expression, the miRNA TaqMan arrays offer researchers the accuracy, sensitivity, and reproducibility of real-time PCR PCR polymerase chain reaction.

MicroRNAs are non-coding RNA molecules that regulate gene expression. They play a role in developmental and cell biology, including stem cell stem cell

 in a number of different diseases, including cancer and neurological disorders. Research related to microRNAs is one of the fastest growing areas in biology. Previous research has shown that by profiling expression patterns of miRNA genes, scientists can identify potential miRNA biomarkers that classify different disease types and identify disease susceptibility. Applied Biosystems designed the new miRNA TaqMan arrays to help researchers perform large-scale gene expression profiling of miRNAs, and simultaneously detect and determine the amounts of up to 365 different miRNA genes that may be present in biological samples.

The miRNA TaqMan arrays require lower amounts of starting RNA RNA: see nucleic acid.

The arrays also enable researchers to conduct experiments to evaluate expression changes in miRNA genes normally expressed at levels too low to detect using other methods such as hybridization hybridization /hy·brid·iza·tion/ (hi?brid-i-za´shun)

The specificity of the TaqMan miRNA arrays enables researchers to specifically detect the biologically active mature forms of miRNA molecules and to discriminate between closely related miRNAs, which can help researchers better understand the role specific miRNAs play in a cell.

Fragile X syndrome is the most common form of inherited mental retardation. Individuals with this condition have developmental delay, variable levels of mental retardation, and behavioral and emotional difficulties.
. By investigating how miRNAs regulate neural stem cell proliferation and differentiation in mouse models of both disorders, Dr. Jin hopes to learn about the role of miRNAs in human disease pathology. He noted that he used the TaqMan Array Human MicroRNA Panel to detect miRNAs in mice, because a significant number of human and mouse miRNAs are the same.

"Our sample throughput has increased dramatically," said Dr. Jin. "Before we had access to the TaqMan arrays, we could only analyze about two samples a day. We can now analyze these same samples in about two hours. The use of this technology has greatly increased the number of miRNAs we can screen per sample and the number of samples we can screen in a day."

The TaqMan Array Human MicroRNA Panels are part of a complete system that enables researchers to perform 384 simultaneous real-time PCR reactions without requiring liquid-handling robots or multi-channel pipettes. To perform miRNA gene expression analysis, researchers add DNA DNA: see nucleic acid.

"Although the discovery of microRNAs is a relatively recent event, and there is still much to learn about their mechanism of action, research continues to reveal the significant role they play in a variety of fundamental cellular processes," said Peter Dansky, vice president and general manager for Applied Biosystems' molecular and cell biology consumables business. "With these new miRNA TaqMan arrays, researchers have fast, highly-sensitive tools with which to perform large-scale profiling of these important molecules and learn more about their biological role."

Applied Biosystems is a global leader in the development and commercialization of instrument-based systems, consumables, software, and services for the life-science market. Combined with miRNA isolation kits and analysis products from Ambion, Inc., an Applied Biosystems business, the company offers one of the life-science industry's most comprehensive lines of microRNA analysis tools. The miRNA TaqMan arrays, along with a complete line of TaqMan([R]) array gene signature panels and more than 700,000 individual TaqMan([R]) Gene Expression Assays are available on the Applied Biosystems website.
