We offer proteomics services based on liquid chromatography-tandem mass spectrometry (LC-MS/MS), covering sample preparation, digestion, chromatographic separation, mass spectrometric detection, and data analysis — usable for whole-proteome expression profiling, differential protein screening, and post-translational modification analysis.
When you want an unbiased, whole-proteome view of exactly which proteins changed before and after treatment, rather than focusing on a single known protein, mass-spectrometry-based proteomics provides a panoramic protein expression map — answering "besides the protein I’m focused on, which other proteins also changed."
Protein samples are digested into peptides, separated by high-performance liquid chromatography, and detected by MS1/MS2 fragmentation in the mass spectrometer. Sequence identification and quantification are based on peptide mass-to-charge ratios and fragmentation spectra, enabling deep-coverage analysis of thousands of proteins.
Differential protein screening, modification proteomics, interacting complex analysis, biomarker discovery, etc.
