Service Description
We have developed innovative solutions for optimizing the process of accurately quantifying proteins in complex biological matrices and other complex mixtures.
Isobaric Label TMT Quantitation Proteomics
Isobaric Label services incorporate sample multiplexing to provide deep proteome coverage and highly precise quantitation of small or medium-sized sample sets. Samples are prepared and labeled separately, then all samples are pooled and analyzed by nano-flow LC-MS/MS1.
Project Workflow
BGI Genomics provides Isobaric Label Quantitative Proteomics service using TMT (Tandem Mass Tags for Quantitation) technology developed by Thermo Fisher Scientific.
- Protein extraction
- Protein digestion
- Isobaric labeling
- HPLC fractionation
- LC-MS/MS (DDA)
- Data analysis
