Eurogentec of Seraing, Belgium, has recently introduced whole-genome microbial microarrays for Bacillus subtilis and Helicobacter pylori. These arrays, available on nylon or glass slide, are for distribution in both Europe and the US although the company does not yet have a US distributor. The company plans to introduce a Drosophila melanogaster array and seven additional microbial arrays in the next two to three months. These arrays include Neisseria meningitidis, Streptomyces lividan, Saccharomyces cerevisiae, Streptococcus pneumoniae, Streptococcus thermophilus, Schizosaccharomyces pombe, and Escherichia coli pathogen strains. Ordering information is available on the company’s website, www.eurogentec.com.

 

Silicon Genetics of Redwood City, Calif., is sponsoring training workshops for its GeneSpring microarray data-mining software in the coming month. The beginners’ training workshop will take place February 18th and 19th in Redwood City, Calif., and intermediate training will occur February 5th and 6th in New Orleans and in Redwood City, Calif., on February 20th and 21st. Advanced training will take place February 22nd in Redwood City. For more information, go to www.sigenetics.com.

 

Digene of Gaithersburg, Md., has launched its Hybrid Capture ExpressArray Kit, an assay for gene expression on microarrays. Based on Digene’s patented Hybrid Capture technology, the new kit is designed to enable users to run microarray experiments on thousands of genes at once, in hours compared to days, the company said.

The kit does not use labeling or amplification, and allows users to perform assays on less than one microgram of tRNA, according to Digene. More information is available at www.digene.com.

 

Lambda and Greiner bio-one of Friestadt, Austria, have developed the Paro Check, a chip they advertise as the first-ever biochip for detection of pathogens involved in periodontitis. The Paro Check includes 96 DNA spots on coated glass slides, and is designed to enable screening of 20 different bacterial pathogens related to periodontal disease. The chip also includes an internal control system to avoid false negatives and false positives, and according to a study by the companies involving detection of periodontitis, is sensitive enough to detect as few as 1,000 copies of the pathogen genes. For more information, go to www.lambda.at or www.greinerbioone.com.

 

LaVision BioTec of Bielefeld, Germany, has introduced TriMScope, a new multifocal multiphoton laser scanning microscopy device. “This is the first microscopy instrument where you can see a two-photon image through the eyepiece,” said Bernd Muller-Zulow, a sales manager for the company. The device includes a patented beam multiplexer, which allows multifocal set ups. The device costs about $300,000 including the laser.
