GeneXP Biosciences of Woburn, Mass., this week announced the launch of the 96-well Rat Gene BioGridArray (BGA), designed for rapid gene-expression studies of toxicity. GeneXP developed the Rat Gene BGA by choosing genes regulated in response to stress or exposure to toxicants, according to publicly available data. Each well of the BGA microplate contains the same array of 173 genes printed in duplicate as well as a number of housekeeping and control genes. Complete annotation is also provided for each gene to facilitate the interpretation of data. The Rat Gene BGA is currently available as part of GeneXP Biosciences’ outsourced service for gene-expression studies, or as an installed solution in customer labs. Pricing details were not disclosed.


Genomic Solutions this week introduced HydroShear, an automated system for fragmenting DNA strands. The software driven product shears DNA in volumes as small as 40 microliters and randomly fractures it to within a two-fold size distribution consistently.
