2. Protein Separation

Sample Preparation: Cells from colon cancer line HT116 were lysed in 8M urea/100mM Ammonium bicarbonate buffer. The equivalent of 60,000 cells were loaded onto an 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.
