Proteomics

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

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.
