Illumina this week launched its HumanHT-12 BeadChip, a 12-sample product designed for use in whole-genome expression and expression-based quantitative trait loci studies.
 
The HumanHT-12 BeadChip includes more than 48,000 probes per sample and is priced at $75, supporting a total cost of $100 per sample including labeling reagents, the company said.
 
Illumina expects to commence shipment of the HumanHT-12 this quarter.
 

 
Mobidiag this week launched its Prove-it Bacteria test, an array-based diagnostic that can simultaneously detect 50 bacteria associated with infectious diseases.
 
According to Helsinki, Finland-based Mobidiag, Prove-it Bacteria is initially intended for research purposes though the firm expects to file for a CE Marking in Europe later this year.
 
BioArray News spoke with Mobidiag about its diagnostic plans last month (see BAN 3/25/2008).
 

 
Pathwork Diagnostics this week announced the launch of its Pathwork Tissue of Origin Test through its CLIA-certified Pathwork Diagnostics Laboratory.
 
Pathwork said the test measures the expression of more than 1,500 genes to compare a tumor’s gene-expression profile to those of 15 known tissues, representing more than 60 morphologies, and to provide an objective, probability-based score for each potential tissue.
 
The test runs on Affymetrix’s GeneChip System.
 

 
Sigma-Aldrich last week launched its Imprint Chromatin Immunoprecipitation Kit for epigenetic research.
 
The Imprint ChIP Kit includes columns and reagents for DNA purification as well as an integrated protocol for ChIP DNA amplification with Sigma’s GenomePlex Whole Genome Amplification Kit.
 
According to Sigma, the Imprint ChIP Kit can be used with quantitative PCR, MS-PCR, DNA sequencing, and microarray technology.
