Eprogen has introduced its ProteoSep HPLC-based products for separating intact proteins, the company said Jan. 24. The company claimed the technology allows researchers to study proteins with post-translational modifications more easily than comparable HPLC techniques that involve breaking proteins into smaller peptides. “Direct analysis of intact proteins allows for the retention of important biological information that is lost using existing peptide analysis techniques,” the company said in a statement.
Based inDarien, Ill.,Eprogen has also released its ProteoVue software for displaying the separated proteins in 1D and 2D maps familiar to researchers accustomed to viewing 1D and 2D gels. “This integral feature of the software gives scientists the power to more effectively study proteins present in multiple samples and, along with the benefit of liquid fractions, judiciously choose proteins of particular interest for further analysis,” Eprogen said.
Matrix Science has made its Mascot protein identification software available for use with IBM’s AIX 5L UNIX operating system, the London, UK-based company said Jan. 23. It added that the AIX platform is “robust and scalable, providing an ideal platform for high-throughput proteomics studies,” according to a statement.
Innovadyne Technologies and Thermo Labsystems said last week that they plan to commercialize a non-contact, low-volume pipetting instrument for dispensing small volumes of liquid into 384- and 1,536-well plate formats. The product, intended as the next generation of Thermo Labsystems’ Multidrop product line, is derived from Innovadyne’s proprietary fluidics technology, and will target volumes of between 100 nanoliters and 10 microliters. “Working with Thermo Labsystems, we are excited about the potential for our technology to miniaturize HTS assays,” Innovadyne said in a statement.
