Nonlinear Dynamics this week introduced new versions of its Progenesis LC-MS, Progenesis MALDI, and Progenesis SameSpots software.
For the LC-MS product, a new Protein View step calculates protein levels from associated peptides in order to resolve instances when a peptide is associated with more than one protein.
Progenesis MALDI uses the "unique" Progenesis alignment approach, which "allows robust statistical analysis on complete datasets as there are no missing values," the company said in a statement. The software can also be used for SELDI-based analysis.
And new features on SameSpots allow the use of previous experiment information, including protein identifications across experiments.
GE Healthcare this week launched products to improve and simplify the 2D electrophoresis workflow.
The new products include precast low fluorescent DIGE gels and the DIGE Buffer Kit that improve gel-to-gel reproducibility; repackaged CyDye DIGE Fluor saturation and minimal dyes "that better suit experimental designs" according to the firm; and reformulated IPG Buffer and IPG strips that improve spot resolution.
InVitria last week introduced the Recombinant Albumin-DX and Recombinant Albumin-DX (Lipid Free) for diagnostic applications.
According to the company, the two products perform better than both bovine serum albumin and plasma-derived human serum albumin. Advantages include the reduction of non-specific binding and improved specificity; improved consistency; and improved stabilization of sensitive proteins and biomarkers.
Customer testing has resulted in biomarker activity twice that of other commercial alternatives, InVitria said in a statement.
Based in Fort Collins, Colo., the company develops and manufactures reagents and cell-culture products.
