Protein identification service
With the advancement in mass spectrometry technology, protein and peptide
identification is no more tedious and time consuming. To help shorten the time
duration of protein identification and enhance the accuracy of protein
sequencing, Creative Proteomics has been long focused on optimizing our
mass spectrometry technology platform. We have developed a comprehensive
protein identification pipeline, which starts from sample preparation, protein
separation and purification, followed by mass analysis, and finally to
systematic bioinformatics analysis.
The following picture illustrates a typical workflow for protein identification and
characterization using MS/MS data. The starting point is a given protein
sample that may be a single protein or a complex mixture of different proteins.
An enzyme, often trypsin, is used to digest the proteins to peptides. In most
cases, one or more stages of chromatography are applied to regulate the flow
of peptides into the mass spectrometer. Peptides are then selected for one at a
time in the first stage of mass analysis. Each isolated peptide is induced to
fragment by collision in the second stage of mass analysis. The fragments are
captured to synthesize a MS/MS spectrum.
