Subcellular Structures Protein Identification

Knowledge of all the protein components of a particular subcellular component is very useful for specific studies of the functional unit of the structure. With an advanced mass spectrometry platform and rich experience in protein identification, CPR can provide you with a comprehensive range of subcellular structural protein and organelle protein identification services.

Advantages of Organelles and Subcellular Structures Protein Identification Services:

  • Rich proteomics experience. The company has been engaged in proteomics related services for 16 years.
  • Professional Platforms. High-resolution Q Exactive Hybrid Quadrupole-Orbitrap mass spectrometer is available.
  • Bioinformatics services. Our bioinformatics analysts can help you interpret the final data.
  • Custom services. Based on your samples and requirements, customized solutions can be customized for you.

Methods of Organelles and Subcellular Structures Protein Identification:

In combination with our mass spectrometry platform, we can use a variety of techniques to identify subcellular component proteins.

1. Peptide Mass Fingerprinting Protein Identification Service
Analytical techniques for identifying unknown proteins to determine the quality of peptides. The results were obtained by comparing the determined peptide mass with a database of theoretical peptide masses for all known protein sequences.

2. Shotgun Protein Identification Service
Multiple proteins can be identified simultaneously. The peptides were separated by high performance liquid chromatography, and then combined with tandem mass spectrometry for peptide sequence analysis.

3. Top-Down Mass Spectrometry Service
Top-down mass spectrometry does not require enzymatic hydrolysis and can identify intact proteins. This method has higher sequence coverage and is helpful for protein post-translational modification analysis.
