Definiens, Advion BioSciences

Premium

Definiens introduced this week version 3.0 of Proteomweaver, a software for analyzing 2D-gel electrophoresis images.

The latest enhancements to the product include advanced metadata handling to annotate experiments, tissue, experimenter, sample preparation, staining, sequence and mass spec data. A search engine helps the user to retrieve experiments according to their annotations.

Other new features include enhanced spot labels and comprehensive XML/HTML-based reports with information on spot statistics, parameter settings and analysis sets.


Advion BioSciences has released its nano LC column-to-chip coupling and Advanced User Interface software — two new enhancements for its NanoMateR HD System technology.

Designed to work with all commercially available 75-micron columns, the nano LC column-to-chip coupling feature provides sub- fmol detection limits for protein identification and the ability to minimize risk of sample loss by changing to a new sprayer nozzle during acquisition, the company said.

According to Advion, the new AUI software allows researchers to mix protein and ligand prior to infusion for automated Kd determinations as well as controlled incubation time and temperature prior to analysis.
