The European Molecular Biology Laboratory’s European Bioinformatics Institute said recently that its ArrayExpress database has doubled in size to contain transcriptomics data from 100,000 hybridizations.
The database now holds snapshots of gene-expression signatures for more than 180 species taken under thousands of experimental conditions. According to EMBL-EBI, the latest data increase reflects the mass import of data from the Gene Expression Omnibus database.
NanoString Technologies this week launched an early-access program for its nCounter Analysis System for digital gene expression. CalTech was its first customer.
The nCounter uses molecular barcodes and single-molecule imaging to detect and count hundreds of unique transcripts in a single reaction. According to NanoString, it is ideally suited for researchers with small amounts of starting material, customers who would like to study defined gene sets, and microarray users seeking to validate expression signatures.
Febit and Prognosys Biosciences this week officially launched their Genome-to-Array Service that enables users studying microbial organisms to go from biological genetic material to a working microarray experiment in weeks.
La Jolla, Calif.-based Prognosys Biosciences will sequence the DNA using an Illumina Genome Analyzer, while Febit will synthesize arrays using its Geniom microarray technology, the companies said.
Febit and Prognosys previously discussed the service with BioArray News in September (see BAN 9/25/2007).
