2. Protein Separation
Sample Preparation: Cells from colon caner line HCT 116 were lysed in 8M urea/ 100mM ammonium bicarbonate buffer on ice. The equivalent of 60,000 cells were loaded onto a SDS gel. The protein of interest was excised and ingel digestion with trypsin was performed after reduction and alkylation with TCEP and IAA. 1/6 of the resulting digest was then analyzed on a Thermo Scientific TSQ mass spectrometer.
3. LC-MS/MS Data
EAFLVPAYTEQSQIK
No LC-MS/MS for this peptide.
4. LC-MRM Screening
Peptides screening: Peptides and transitions for analysis were selected using a predictive peptide program. The results were screened for those with the highest specificity and the most intense transitions.
