GE Healthcare, Rosetta Biosoftware, Stanford University School of Medicine

GE Healthcare last week launched the DeCyder 2D 7.0 software for analysis of 2D fluorescence difference gel electrophoresis experiments.
The software applies a gel comparison method that introduces zero statistical error, “offering reliable data and analysis for 2D DIGE experiments,” the company said in a statement. A unique co-detection algorithm reduces false positives and false negatives, increasing throughput, and reduces hands-on time from days to minutes.
The software was developed specifically for 2D DIGE and is a “key” component of the Ettan DIGE system, GE said.

Rosetta Biosoftware this week introduced Elucidator version 3.2.
New features provide workflows for biomarker discovery, verification, and validation in basic and translational research, the company said in a statement.
Enhancements include support for SILAC and (14)N(15)N-labeling. Also, new data analysis workflows allow for the discovery of all types of post-translational modifications, including those related to phosphoproteomics.

Arend Sidow, an associate professor of pathology and genetics at the Stanford University School of Medicine has launched ProPhylER, a free online database that enables researchers studying proteins, and the genes coding for them, to ascertain how each protein works and whether a gene mutation will lead to problems down the road.
According to a statement, ProPhylER “enlists evolution as the guide to determining the role different proteins play in a wide array of organisms.” The database allows biologists to see which parts of a protein are crucial to its activity by comparing versions of the same protein from different species. This function is especially useful for proteins for which little or nothing is known, the university said.
ProPhylER, which debuted Oct. 10, is available here.
