General Electric Healthcare s CodeLink Mouse Whole Genome Bioarray, NimbleGen Systems ENCODE Microarray Service, and Nucleics Pty s CounterTrace II


General Electric Healthcare released its CodeLink mouse whole genome bioarray this week, which features the entire mouse genome for use in gene expression profiling, the company said. The array contains “approximately 35,000” probes targeting more than 36,000 mouse transcripts, the company added.

NimbleGen Systems this week launched its ENCODE microarray service, which uses “more than 384,000” unique 50-mer probes from among 30 megabases of human sequence data specified by the ENCODE Project Consortium, the company said in a statement. The probes are tiled every 38 bases, creating a 12-base overlap between each, a design which has been used in mapping transcription factor-binding sites and chromatin structure, the company said.

This week, Nucleics Pty introduced its CounterTrace II DNA sequencing system, which is composed of a DNA standard that can be “specifically” detected in four-channel sequence data, and a DNA trace reprocessing software package, the company said in a statement. The system increases the number of high-quality bases obtained by ABI3170 and 3730xl instruments by “up to 30 percent,” when used with KB v1.1 basecaller, the company said.
