Thermo last week introduced GRAMS 8.0, an update to its multi-vendor spectroscopy software. The software interfaces with more than 150 instruments and “enhances GRAMS’ workgroup and enterprise connectivity via a full client/server update to Spectral DB, and features the all-new Web-enabled Envision viewing and reporting tool,” the company said.

Sigma-Aldrich launched the PhosphoProfile I phosphopeptide enrichment kit this week. The technology is based on a novel Ga+3 chelate on silica that “provides a robust method for phosphoproteomics,” Sigma-Aldrich said in a statement.
According to the company, advantages offered by the technology include very low, non-binding, non-bias in selectivity of phosphorylation state, high sensitivity, and fast sampling.

Bio-Rad made available this week its ProteOn XPR36 Protein Interaction Array System, an SPR imaging optical biosensor.
ProteOn XPR36 uses image analysis to track optical changes at many different sites in an image with high sensitivity but without the need for molecular labeling, Bio-Rad said. The instrument provides “the ability to understand protein interactions with the efficiency, flexibility, and versatility of parallel processing,” the company said.

NextGen Sciences launched this week a new range of optigel 2D gels available in different gradients and supports. Optigels are available with standard or low fluorescing glass plates “to allow compatibility with both traditional and fluorescent labeling systems,” the company said.

Proteopure launched this week its ProteoHook 2DE Sample Preparation Kit for use in preparing samples for 2D gel electrophoresis. The company said the kit can be used with any sample type. The kit uses spin columns and includes all necessary buffers.

Syngene said this week that its Dyversity image analyzer can detect 0.5 ng of Sypro Ruby stained protein in less than a second, making it applicable for high-throughput gel-based proteomics. Dyversity has a 90-micron resolution, 16-bit CCD camera, giving it the fastest capture time per channel for Cy dyes of any CCD system on the market, the company said.
