GE Healthcare last week introduced the Dextrin Sepharose High Performance and StrepTacin Sepharose High Performance affinity chromatography media.
 
Each contains evenly sized 34 micromolar Sepharose High Performance beads that ensure that proteins elute in narrow peaks, minimizing the need for additional concentration steps, GE said in a statement.
 
The Dextrin media is designed for the purification of proteins tagged with maltose binding protein while StrepTactin is designed for Strep-tag II fusion proteins.
 

 
Protein Forest last week launched the digital ProteomeChip System at the American Society for Mass Spectrometry conference in Denver.
 
The ProteomeChip technology fractionates proteins or peptides by parallel isoelectric focusing on dPC chips for mass spec analysis and Western blotting. dPC chips are manufactured to have a difference of .05 pH units between adjacent gel plugs with guaranteed reproducibility, Russell Garlick, president and CEO of Protein Forest, said in a statement.
 

 
BioInquire last week released ProteoIQ software for analysis of proteomic data.
 
The software supports the entire proteomic data analysis pipeline including data organization, statistical validation, protein quantification, and publication/collaboration, the company said in a statement. In particular ProteoIQ is well-suited for analyses where spectral counting-based quantification is combined with data mining functions, allowing researchers to find differences between multiple proteomic data sets, it added. 
 

 
Sidec last week released a new version of its Protein Tomography technology for the analysis of therapeutic antibodies and drug targets in biological systems.
 
The technology uses regularization theory to create a 3D image from a series of 2D electron microscope images. The enhanced method improves the investigation of the structure and interactions of macromolecules in solution and in cell tissue samples, Sidec said in a statement.
