Proteomics Services — Discovery to Validation

 

DIA, PTM, 4D and PRM targeted proteomics: with Orbitrap high-resolution mass spectrometry as the core platform, projects run from large-scale discovery to targeted candidate validation as a closed loop, delivering protein quantification matrices and bioinformatics reports.

## FAQ

 FAQ 
 How long does a Proteomics project take? Standard proteomics projects take 3-5 weeks depending on sample number and analysis depth; key milestones (sample QC, LC-MS/MS completion) are proactively synced with you. How should proteomics samples be stored and shipped? Store at -80°C and ship on dry ice; avoid repeated freeze-thaw cycles. Protease inhibitors are recommended for protein samples. A tailored Sample Collection Guide is provided before shipping. How can DIA proteomics results be validated? We recommend PRM targeted proteomics for candidate validation (antibody-free, highly reproducible), or classic assays such as Western Blot and ELISA, forming a "discovery → validation" closed loop. What samples do you need for Proteomics? Cells ≥1×10⁶, tissue ≥50 mg, serum/plasma ≥50 μL, FFPE ≥4 sections (5 μm). Protein samples tolerate freeze–thaw poorly — aliquot so each tube is thawed once; for PTM work include matched controls and avoid phosphate buffers. See Technical Resources → Sample Guide .
