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

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.
