Beckman Coulter of Fullerton, Calif., has introduced its ProteomeLab PA-800 protein characterization system for the automated, high-resolution analysis of proteins. The system offers molecular weight determination, peptide mapping, isoelectric focusing, carbohydrate profiling, and mechanisms to study protein-protein interactions in solution. It is based on Beckman’s automation and capillary electrophoresis technologies. The PA-800 includes chemistry, software, training, and support.
Furthermore, the company released ProteomeLab PF 2D, an automated, two-dimensional fractionation system for high-resolution analysis of complex protein mixtures. In the first dimension, chromatofocusing separates the proteins according to their pI. Fractions from the first dimension are collected and automatically injected into a second dimension, which separates proteins on the basis of hydrophobicity. ProteomeLab PF 2D software displays both one- and two-dimensional maps of the expressed protein profiles.
Both the PA-800 and PF 2D systems can be linked by the company’s 32 Karat software, a central platform providing instrument control and data analysis.
