PerkinElmer has launched a new non-contact micro-dispensing system called Piezoarray. The system features a computer interface that is much easier to use than previous machines in designing custom array plates, according to the company. Droplet microvolumes are precisely controlled by a patented piezoelectric tip technology that dispenses reproducible volume droplets.

GenTel Biosurfaces launched this week its new PATH Protein Microrray slide for quantification and characterization of proteins. The 3” by 1” slide features an ultra-thin, non-porous nitrocellulose film that is suitable for protein microarray applications. According to Gentel, the special surface allows for high protein retention and low background noise.

Incyte’s Proteome database division is throwing its hat in the pathway informatics ring with the launch of a new module for its BioKnowledge Library.

Matt Crawford, director of curation technologies at Incyte, said that the Proteome curators started with an initial set of 300,000 papers, 18,500 human proteins, and 251,000 “conceivable interactions.” Using Reel Two’s text-mining software, the curators narrowed that set to around 100,000, of which only around half are expected to be “real interactions” following manual curation, Crawford said.

So far, the module contains 26,000 interactions, including protein-protein interactions and regulatory and modification events such as transcriptional and post-translational modifications. PSD Interactions also offers a graphical browser called the BioKnowledge Workspace for visualizing interactions.

Applied Biosystems announced this week the launch of its LS*LIMS Software that integrates data from many different sources for genomics and proteomics laboratories.

The new software integrates an expanding number of ABI and third-party instrument interfaces, including the ABI 3730 and 3730xl DNA analyzers, ABI PRISM 7900 HT and the GeneAmp PCR System 9700.
