Pan Human 10K Array, Compact Gene Index, Scan Array Express, NOMAD


MWG Biotech of Ebersberg, Germany and High Point, NC, has launched the Pan Human 10K Array, a 10,000-spot human array and the first of a three-array set that will cover the 30,000 identified human genes. The company plans to release the other two human arrays in the first quarter of 2002.

The Pan Human 10K array represents human genes of known function, and uses oligonucleotide probes. The oligonucleotides on the array are also available as a 10K oligo set that can be used by researchers to spot their own microarrays. Additionally, the company has developed a database, the Compact Gene Index system, which allows users to search for genes or gene functions that are included in the array.

This new product adds to MWG Biotech’s portfolio of catalog arrays, including its Chromosome 21 Array, which has 500 genes, and the Pan Human Cancer Array, which includes 1,900 genes relevant to cancer. The company also plans to provide custom arrays for researchers who would like to do more targeted research.


Packard Biosciences, a Meriden, CT division of PerkinElmer Life Sciences, has recently added the Scan Array Express scanners to its product lineup. The Scanners include the ScanArray Lite, which is sold at a list price of $46,350, the ScanArray Express, which sells for a list price of $56,500, and the ScanArray Express HT, which sells for $76,500.

The ScanArray Lite is a two-color scanner that has a single-slide feed and can be used with all dyes that are excited by 543 nm and 633 nm wavelengths. The ScanArray Express offers up to five-colors out of six possible wavelengths, can be upgraded with higher quality lasers and also has a single-slide feed. The Scan Array Express HT includes a 20-slide autoloader that can notify the user via e-mail when the batch is complete.

“These products build on the ScanArray line,” said Randall Morse product manager at Packard Biochip technologies. “They still offer the upgradability feature in terms of being able to do more than two-color arrays, and there are quality control features so users can do quality checks on arrays pre-hybridization to see if they have DNA in the spots.”

The ScanArray Express models all include ScanArray Express 1.0 software, which combines data acquisition and analysis, and outputs both GPR and CSV file formats.


University of California, San Francsico computer scientists have released the first Alpha version of NOMAD, an open source system for storing and querying the results of microarray experiments. The software is available for free download at http://ucsf nomad, and can run on any Unix-like system, including Linux and Mac OS X.
