Proteos offers the following mass spectrometry services from Protea:

MALDI Intact Analysis

Intact protein molecular weights are quickly and accurately determined using the Bruker UltraFlextreme MALDI-TOF/TOF. 

LC-MS Intact Mass

Intact protein molecular weights are accurately determined using a variety of LC-MS instrumentation including Thermo Scientific QExactive or Agilent 6530 Q-TOF.

Peptide Mapping

Proteins are digested with trypsin/Lys-C (or other enzymes as required) to produce the peptide maps for follow on LC-MS/MS analysis.  Additional sample preparation steps can be taken to provide sequence coverage of N- and C-terminal residues and post translational modification variant analysis.  

Mass spectrometry services can be ordered individually or add to any protein production analytics package.  Requests for individual analyses or protein production services can be requested through the “Request Quote” link below.
