Protein identification can be performed on a variety of samples, including protein gel spots, protein gel bands, IP samples, etc. Proteins are analyzed either by MALDI-TOF/TOF or by nano-LC-ESI-MS/MS and then identified using peptide masses or MS/MS fragmentation spectra. We provide your protein identification results in an electronic report that also includes bioinformatics analysis results, such as GO and pathway analysis. For RMM >6000amu LC/MS is preferred.


  • High resolution and accuracy: With LC-MS/MS, the accurate identification results can be provided based on resolving power up to 100,000 FWHM and 1 ppm mass accuracy.
  • Ultra-fast scanning speed: UltrafleXtremeTM MALDI-TOF/TOF MS with 1 kHz smartbeam IITM laser technology can provide fast spectra collection in both TOF and TOF/ TOF modes.
  • High sensitivity: Able to detect proteins at even nanogram levels.
  • Protein identification aims to identify peptides and proteins from gel spot samples or gel band samples. It can provide necessary fundamental knowledge for further proteomics analysis.


Sample Requirements for Protein Identification:

  • Gel band: the amount of proteins ≥30µg, concentration ≥1µg/µl. The gel band needs to be visible with coomassie blue or silver staining.
  • Gel spot: the amount of proteins ≥50pmol. Salt content: volatile inorganic salt < 20mM, stable inorganic salt < 5mM.
  • Protein molecular weight detection:
    • Sample type: purified protein solution or powder (the purity of the sample should be > 90%)
    • Total amount of protein: ≥50ug
    • Protein concentration: ≥1ug/ul
  • If silver staining method is used, please be sure not to fix the gel with glutaraldehyde.

Sample Preparation:

1. Sample preparation: enzymolysis
2. MS analysis strategy:
2.1 gel spot samples: ultrafleXtreme MS analysis
2.2 gel band samples: LTQ-Orbitrap velos MS analysis
