Proteome Sciences, Phoenix S&T

Proteome Sciences this week officially launched its Tandem Mass Tags isobaric mass tagging reagents with workflows and applications. The company received a US patent for the technology earlier this month [See PM 11/22/07]. Applications include the TMT calibrator for absolute quantification of multiple biomarker proteins and TMT Reference Materials for relative quantification of proteins in large and complex biomarker programs.

Phoenix S&T this week launched its SureSpray AutoNano System for robust and high-throughput protein and metabolite analysis. The system uses a 16-nozzle chip for nanoLC-MS and direct infusion-MS. It robotically connects a capillary LC column to a nozzle in the chip and ensures uninterrupted spray “during the entire gradient chromatographic run with an active spray control mechanism that regulates the electrostatic field for a stable spray,” the company said in a statement.
Phoenix S&T develops and sells injection-molded devices for mass spectrometry applications.
