MWG-Biotech of Ebersberg, Germany, has released a new rat microarray containing 10,000 genes in total. In addition to 5,535 genes from public databases, the chip contains 4,105 genes from an in-house EST sequencing project covering brain, heart, liver, and kidney tissues from three rat strains: SHRS, stroke-prone spontaneously hypertensive rats; WKY, wistar kyoto rats; and SD, sprague dawley rats. For scientists wanting to spot their own arrays, the oligo set is available separately.
Amersham Biosciences has launched an automated microarray hybridization station called Lucidea SlidePro Hybridizer. The system automates slide pretreatment, non-static hybridization, stringency washes, and slide drying. It includes one to five modules, each containing six hybridization chambers, and allows users to process up to 30 slides at a time. The station is also suitable for slide processing applications such as protein arrays, in situ hybridizations, and immunocytochemistry.
Takara Bio of Kyoto, Japan, and Madison, Wis.-based Mirus have launched the Takara-Hubble Slide, a glass slide for DNA microarrays. Its surface possesses an amino-reactive ester, to which DNA fragments such as synthetic oligonucleotides as well as polynucleotides with several hundred bases can be attached.
TIGR’s array software team released its informatics suite, TM4, under an open source license last week. TM4 comprises four packages: MIDAS (Microarray Data Analysis System), a microarray data normalization and filter tool; MADAM (Microarray Data Manager), an application designed to load microarray data into a database in a MIAME-compliant manner; Spotfinder, an image processing program; and MultiExperiment Viewer (MeV), a data mining and visualization tool.

Schleicher & Schuell BioScience of Keene, N.H. has launched its ProVision Human Cytokine Array. The array allows to screen for 16 human cytokines and each slide contains eight pre-printed antibody arrays. The product uses the FAST slide 3D nitrocellulose surface.
BioChipNet, which is administered by the NMI in Reutlingen, Germany, has launched a monthly e-mail newsletter with press releases, company facts, and conference information from the biochip industry, featured on its portal at www.biochipnet.de.
