Affymetrix this week launched its GeneChip Human Gene 1.0 ST Array. The company did not disclose the price for the new array, but said it’s available at a lower price than its Human Genome U133 Plus 2.0 Array and targeted toward academic users. and targeted toward academic users.

In the Human Gene 1.0 ST Array design, each of the 28,869 genes is represented by a set of approximately 26 probes. This company claims that this design strategy provides one value from one probe set for each gene, yielding a more accurate representation of all of the transcription activities for each gene of interest than traditional designs.

Affy also recommends the use of the Human Gene 1.0 ST Array with its Expression Console Software to simplify the analysis workflow.

HTG last week launched its bench-top, chemiluminescent imager, the FireFly Imaging System, for use with its quantitative nuclease protection assay kits for measuring gene expression. The system optimizes imaging for HTG's ArrayPlate qNPAT technology, a high-throughput array that enables multiplexed measurement of RNA levels, DNA expression, and protein function.
Â
The FireFly includes a CCD camera that can image multiple targets for an entire 96-well plate in about 15 minutes, HTG said. FireFly technology is suitable for a wide range of drug discovery and molecular diagnostic applications such as target gene validation, gene expression screening and time course studies, the firm added.
