Varian has introduced its PursuitC8 column for reverse phase high performance liquid chromatography and LC/MS applications. The column has enhanced separation abilities and rapid separations, and will enable users to have faster run times, improved peak symmetry, and enhanced selectivity, the company said.

The company has also introduced an 800 MHz Cold Probe for proteomics and structural biology research. This cold probe is already being used at the National Magnetic Resonance Facility in Madison, Wisconsin, the company said. “The Varian 800 (NMR spectrometer) and Cold Probe provide by far the highest sensitivity of any of our systems along with remarkably good solvent suppression,” John Markley, the Head of NMRFAM, said in a statement.


Dynal Biotech has launched its Dynabeads Talon product for histadine-tagged proteins. The company said the product’s bead surface facilitates “extremely” low non-specific binding of proteins, and that the beads produce reproducible results, enable quick cleanup of small amounts of a proteins, and are especially suited to pull-down of large protein complexes.


The MathWorks, of Natick, Mass., has introduced its Bioinformatics Toolbox for MATLAB. The product is designed for analysis of bioinformatics data, including proteomics data, and to speed the development of algorithms.

The Bioinformatics Toolbox is being sold for Windows, UNIX/ Linux, and Macintosh systems. Pricing starts at $1,000.


Pierce Biotechnology has introduced its ProFound Protein Interaction Mapping kit. The kit cuts peptide bonds using artificial protease activity. It includes Fe(III) [S]-1-[p-Bromoacetamidobenzyl] ethylene diamine tetraacetic acid, or FeBABE, a labeling reagent that consists of a chelated iron atom linked to a sulfhydryl-reactive moiety (Bracetyl). The reagent set has pre-formulated and pre-measured reagents, for better control over the reaction than is possible through use of traditional reagents.
