The Finnigan vMALDI Ion Source system provides fast, automated MS and Data Dependent MS/MS analysis of digested protein mixtures in a single, rapid experiment. While LC/MS analysis times are typically 30 to 60 minutes, using the Finnigan LTQ with the vMALDI ion source generally requires less than a minute per sample enabling high throughput protein identification.
The Finnigan vMALDI Ion Source
Thermo's new Finnigan vMALDI ion source option for the Finnigan LTQ mass spectrometer creates a revolutionary new option for high throughput protein identification. This integrated system combines the speed of MALDI with the sensitivity of the Finnigan LTQ to create SEQUEST-searchable MS/MS spectra for confident protein assignments.
Finnigan vMALDI Features
The Finnigan vMALDI features the following components:
96- and 384-position sample plates for sample analysis productivity and flexibility
Full integration with the powerful, intuitive Xcalibur data system for seamless operation
Automated targeting using the Crystal Positioning System (CPS) for ease-of-use
Automatic Spectral Filtering (ASF) permits assessment of real-time data quality
Automatic Gain Control (AGC) laser operation maximizes creation of protein information
