Protein identification using mass spectrometry is a very powerful tool and very versatile. First of all you can use it identify or verify a single protein. However, you can also identify multiple proteins in complex samples. The analysis works equally well for both in-gel samples or in-solution samples. The service consists of a digest of protein material using a protease, followed by MS and then MS/MS sequencing.
The protein identification is made by matching the obtained data to the public protein database from UniProt. This is the best database available, as it contains more than 100 million known protein sequences from thousands of organisms.

First, we perform an in-gel or in-solution trypsin digest, followed by a peptide analysis by LC-MS/MS. Afterwards, we search your data against a protein sequence database, with more than 100 million protein sequences. Thus, we can make an very accurate protein identification.
It is also possible to perform a peptide identification by MS and MS/MS sequencing. Our analysis works only for in-solution samples. To get an accurate identification of the peptides in your solution, we search the acquired MS data against the UniProt database.

We perform LC-MS analysis of your in-solution samples. Thereby we identify either a single peptide or multiple peptides in the complex solution.
