NEWPORT BEACH Newport Beach, residential and resort city (1990 pop. 66,643), Orange co., S Calif., on Newport Bay and the Pacific Ocean; inc. 1906. It is a popular seaside resort and yachting center. Manufactures include electrical and medical equipment, computers, boats, and adhesives. , Calif.--(BUSINESS WIRE)--March 1, 2004

Acacia Research Corporation (Nasdaq:CBMX)(Nasdaq:ACTG ACTG Acting
ACTG AIDS Clinical Trial Group
ACTG Actuating/Actuator
) announced today the launch of CombiMatrix group's CustomArray(TM) DNA Microarray DNA microarray

A small solid support, usually a membrane or glass slide, on which sequences of DNA are fixed in an orderly arrangement. DNA microarrays are used for rapid surveys of the expression of many genes simultaneously, as the sequences contained on a
 platform, offering researchers the ability to order fully customizable arrays on demand. Researchers can order CustomArrays by accessing CombiMatrix's order site at www.customarray.com or by contacting CombiMatrix at 800-985-CBMX (2269).

CustomArray is being introduced today to the research market at the annual meeting of the Association of Biomolecular Resource Facilities (ABRF ABRF Association of Biomolecular Resource Facilities ). The ABRF is the single largest gathering of core facility directors and decision makers.

For the first time, customers will have the ability to order fully customizable microarrays in any desired quantity. Researchers simply submit lists of genes, target sequences, or probes. For use with GenBank(R) sequences, data can be specified by accession number Accession number may mean:
  • Accession number (bioinformatics), a unique identifier given to a biological polymer sequence (DNA, protein) when it is submitted to a sequence database.
. GenBank is the leading public repository of the world's sequence data, containing over 22 million sequence entries not only from the human genome The human genome is the genome of Homo sapiens, which is composed of 24 distinct pairs of chromosomes (22 autosomal + X + Y) with a total of approximately 3 billion DNA base pairs containing an estimated 20,000–25,000 genes.  but also from over 130,000 other organisms, including animals, plants, viruses, and bacteria. For use with private databases or when the user has particular probes to put on the array, data can be specified by raw sequence as well.

CustomArray from CombiMatrix greatly simplifies the order and production of custom microarrays, providing microarray users with a fast and flexible option for a wide range of research applications. CustomArrays are produced in a standard slide format, a configuration that is most familiar to researchers. The slide format can be seamlessly integrated into familiar procedures for hybridization hybridization /hy·brid·iza·tion/ (hi?brid-i-za´shun)

 and washing. The slides can be imaged with most existing microarray scanners.

  • Mount Sinai Hospital, New York
  • Mount Sinai Medical Center & Miami Heart Institute
  • Mount Sinai Hospital, Cleveland
  • Mount Sinai Hospital, Chicago
  • Mount Sinai Hospital, Milwaukee
 and CustomArray user said, "CombiMatrix's technology is the fastest and most flexible microarray system available on the market. We anticipate using several different CustomArrays in our ongoing efforts to better understand emerging infectious diseases."

The commercial launch of CustomArray also provides customers with full access to CombiMatrix's suite of software applications, available at www.customarray.com. CombiMatrix has developed user-friendly applications for design submission, online ordering, and extraction of experimental results. Target Specifier(TM) allows researchers to specify the list of genes that will be studied on the array. The list is sent to CombiMatrix's Probe Design System(TM) where probe sequences are automatically designed for that experiment. Microarray Imager(TM) allows a customer to view the experimental results, extract the intensity data, and save the results in standard spreadsheet format.

CustomArray users can look forward to many features including:

-- No subscription or design fee

-- No special equipment required

-- Flexibility to study any genome, any gene, or virtually any

probe sequence

-- Delivery of custom microarrays within 10 days

-- Standard microarray slide configuration

-- Flexible ordering of one or one hundred microarrays

-- Study of multiple genomes on the same chip

CustomArrays are semiconductor-based arrays (approx. 1 cm2) integrated onto a standard 1" x 3" slide format. CustomArrays contain in situ In place. When something is "in situ," it is in its original location.  synthesized oligonucleotides, prepared using CombiMatrix's patented virtual-flask technology. Sensitivity and performance metrics Performance metrics are measures of an organizations activities and performance. Performance metrics should support a range of stakeholder needs from customers, shareholders to employees [1].  are available from the company's web site and at www.customarray.com.
