*Highlighted peptides (with yellow background) have developed assays.
*Green background amino acids are PTMs.

2. Protein Separation

Sample Preparation: Human Serum was digested overnight with trypsin after reduction and alkylation with TCEP and IAA. Sample was then diluted 1:10 for analysis on a Thermo Scientific TSQ mass spectrometer

 

3. LC-MS/MS Data

4. LC-MRM Screening

Peptides screening: Peptides and transitions for analysis were selected from previous LC-MS/MS experiments. The results were screened for those with the highest specificity and the most intense transitions.
