Proteins in the spots were in-gel digested, and peptide-mass fingerprints was obtained by matrix-assisted laser desorption/ionization-time of flight (MALDI-TOF) mass spectrometry (Bruker Daltonic
, MA, USA).
The chromatographic system was coupled to a time-of-flight (TOF) mass spectrometer (MS) (Bruker Daltonic
Bremen, Germany) that was equipped with an orthogonal electrospray interface (ESI; model G1607A from Agi-lent Technologies, Palo Alto, CA, USA) that operated in negative and positive modes of ionisation.
8 million boosted by its defence business through a strategic partnership with Bruker Daltonic
, a supplier of substance detection systems.
introduced its Apex IV FT-MS at Pittcon 2002, which is the next evolution in its Apex series of FT mass spectrometers.
The line-up of companies included such prestigious names as market leaders Millipore, Qiagen, Sartorius, Whatman, Varian, PerkinElmer, Corning, Thermo Fisher Scientific, Bruker Daltonic
