Dutch biotech company Kreatech has launched labeling kits for the DNA microarray market using GE Healthcare’s Universal System Linkage technology. The company said that its first commercially available kits are optimized for labeling of amplified RNA for gene-expression analysis and for labeling of genomic DNA for microarray based comparative genomic hybridization.


Sigma-Aldrich this week launched its Panorama Human p53 Protein Functional Microarray. The p53 protein array was developed by Procognia, and the companies claim that the technology ensures that “the protein is correctly folded and confers full functionality.” The array also includes wild human genome variants, and the companies said that additional arrays will follow.


Gene Logic this week launched ToxShield Suite 1.0, a Web-enabled software platform for assessing and ranking drug compounds based on potential toxicities in humans. Gene Logic said that the software will be used by toxicologists and drug safety scientists at global pharmaceutical companies to aid in their compound development decision-making processes and will be useful in developing screening assays.
