Bruker Daltonics this week launched the solariX, its next-generation hybrid Qq-FTMS instrument for proteomics, petroleomics, metabolomics, and small-molecule drug and metabolite MALDI imaging.
New innovations include improved broad-band mass resolving power delivering eight times more power over earlier platforms, sensitivity greater than 10 times over earlier platforms, and dynamic range. "These dramatic improvements help address today's most challenging top-down proteomics and complex mixture applications," the company said in a statement.
The solariX is the first FTMS with electron transfer dissociation, Bruker added. ETD analysis has been fully automated and can be combined with LC-MS/FTMS workflows in combination with quadrupole fragmentation "to provide unprecedented levels of protein structural information."
GE Healthcare this week introduced the HiTrap Albumin and IgG Depletion and Albumin and IgG Depletion SpinTrap prepacked columns for the depletion of albumin and IgG from human serum and plasma.
The columns remove more than 95 percent of albumin and 90 percent of IgG, the company said in a statement. Separations take about 35 minutes to complete with the HiTrap column for samples of about 150 microliters and above, and about 10 minutes with the SpinTrap columns for samples of about 50 microliters. The HiTrap can also be used for a limited number of repeat runs with consistent depletion rates, GE said.
The columns are prepacked with a mixture of anti-HSA Sepharose High Performance and Protein G Sepharose High Performance.
German protein analysis technology company Caprotec Bioanalytics last week launched the Stauro caproKit for the discovery, identification, and characterization of proteins interacting with staurosporine.
According to Hubert Köster, CEO of Caprotec, the company's data demonstrate that the kit "provides a significant reduction of sample complexity with the associated benefits for mass spectrometric protein identification."
The kit is based on the firm's Capture Compound Mass Spectrometry technology that isolates proteins for analysis that otherwise would be missed.
Staurosporine, originally isolated from the bacterium Streptomyces staurosporeus, inhibits many protein kinases and is widely used for research.
