Beckman Coulter introduced this week a new family of ProteomeLab Partitioning Systems and Chemistries used for sample preparation for the isolation and analysis of protein-based biomarkers. The family includes the ProteomeLab IgY-12 liquid chromatography and spin columns that selectively partition the 12 most abundant proteins from human serum or plasma, which comprise up to 96 percent of protein mass.
The IgY Proteome Partitioning Chemistry is packaged in three formats: a high-capacity LC column that can yield 3-5 mg of enriched proteome per day, a medium-capacity LC column that can yield 0.6-1 mg per day and spin columns that can yield 0.3-0.5 mg per day.
QTL Biosystems said last week that it has introduced its Universal Development Kit for kinase and phosphatase assays. The product release follows the recent launch of QTL’s serine/threonine and tyrosine kinase assay development kits, the company said.
Together, the products provide a platform for developing assays for the two categories of kinases that make up the human kinome, QTL said.
The Universal platform is based on QTL Lightspeed super-quenching technology, the company said. This technology eliminates expensive reagents and hazardous materials required for radiometric- and antibody-based technologies, and will enable the user to use as much as 50 percent less reagents and enzyme to develop an assay, QTL said.
Eksigent Technologies has launched new drivers for its Express LC Control Software v. 2.06 that allow it to integrate seamlessly with Thermo Electron’s Xcalibur mass spectrometry platform, and Applied Biosystems/MDS SCIEX’s Analyst 1.4.1 mass spectrometer platform.
The Express LC is an integrated HPLC system that combines technology for sample injection, gradient delivery and optical detection.
Eksigent also launched new drivers for its NanoLC Control Software 2.06 that allows the software to integrate with Thermo Electron’s Xcalibur mass spectrometry platform, and Applied Biosystems/MDS SCIEX’s Analyst 1.4.1 mass spectrometry platform.
