System is based on chemiluminescence and allows researchers to detect over 31,000 human genes using long, 60bp DNA probes
Applied Biosystems has announced the release of the first gene expression analysis system for whole human genome analysis on a single microarray.
The Applied Biosystems Expression array system is based on chemiluminescence and allows researchers to detect over 31,000 human genes using long, 60bp DNA probes, which promote tighter binding to target molecules.
This combination allows greater sensitivity and specificity compared to other commercially available microarray products and requires less starting material, a big plus when it comes to small, rare or expensive samples.
In addition to the new microarray, the Expression array system comprises the 1700 chemiluminescent microarray analyser, software and reagents.
Customers will also receive an industry standard database of gene names and acronyms, cross references for gene identification, gene ontologies and protein characterisation data from the Panther protein classification system.
Applied Biosystems will continually update the annotations with the most current information that is available about the transcripts targeted by the microarray. Together with the Applied Biosystems Sequence Detection System (SDS) products and the Celera Discovery System online platform, the Expression array system provides a complete and integrated solution for studying changes in human gene expression.
Similar expression arrays for the mouse and rat genomes are due for release in 2004.
