Mass spectrometry is an
analytical technique used to measure the mass-to-charge
ratio of chemical ions. The
UCSC Mass Spectrometry Facility currently houses two mass spectrometers: 1)
a Thermo Finnigan LC/MS/MS (LTQ) and 2) an Ettan MALDI-TOF. This equipment is
capable of determining the molecular weight of both small molecules and peptides,
identifying proteins, and characterizing protein modifications. The facility
is located in Room 339 of the Physical Sciences Building and supervised by Professor
Ted Holman and managed by Mass Spec Specialist Qiangli
(Li) Zhang of the Dept. of Chemistry and Biochemistry.
The facility can be used by UCSC faculty, their
collaborators, as well as outside users. Users must obtain an account name and
a password. New users must first be trained by the Mass Spec Specialist or submit
samples to be run for them. A fee is charged for use.
To reserve machine time, please visit the
PBSCI website for equipment reservation.
UCSC would like to recognize funding support for
the Mass Spectrometry Facility provided by the Thermo Electron Corporation
(Seed funds), the W.M. Keck Foundation (Grant # 001768), NIH's National Center
for Research Resources (SIG # S10RR020939), and the California Institute
for Quantitative Biosciences (QB3).
