Xtra Amp Extraction Kit, GeneDirector, Acuity 1.0, rat cDNA microarray kit


Xtrana of Broomfield, Colo., has released a new Xtra Amp Extraction Kit, which is designed to extract DNA from whole tissues, tissue culture cells, rodent tails, blood stains, and yeast. The kit can digest and extract DNA from rodent tails in 90 minutes — a time improvement over other kits, according to the company. For tissue culture cells, blood stains, and yeast, the kit can go from sample to DNA isolation in 3 to 15 minutes, the company said. More information is available on the company’s web site,


BioDiscovery of Marina del Rey, Calif., has released GeneDirector, its enterprise-wide microarray database system. GeneDirector collects under its umbrella a LIMS system in addition to BioDiscovery’s array design program CloneTracker, its image analysis program ImaGene, and its data mining software GeneSight. GeneDirector supports spotted arrays as well as Affymetrix data, and can be expanded to integrate other genomic and proteomic data.

“One of the novel aspects of GeneDirector is [that] it provides optimized data management for the entire microarray workflow from sample source, sample processing, image analysis through data analysis”, said Soheil Shams, CEO of BioDiscovery in a statement.


Axon Instruments of Union City, Calif., has released Acuity 1.0, a microarray analysis program that is integrated with the company’s GenePix Pro 4.0 image analysis software, and incorporates a searchable database with annotations, experimental parameters, and results. Acuity’s array analysis toolbox includes hierarchical clustering with different similarity metrics, K-means and K-medians, principal components analysis, and other methods. The program allows users to cluster hundreds of microarrays at once.


Agilent Technologies has released a rat cDNA microarray kit, the fourth in its prefabricated cDNA microarray kits. The kit includes over 14,500 unique rat DNA sequences from Incyte Genomics’ clone sets, spread over four microarrays; as well as a hybridization buffer, user protocol, and CD containing the list of features on the microarrays.
