Combining TMT + SILAC sounds like a great idea, right? I will absolutely run that for you if you do the cell culture and the data processing.
Thanks to the nice python scripts in this new preprint, I'd actually consider doing the experiment if I really really like you even if I had to do the data processing. You're on your own on the cell culture. 10-12 passages without contamination? Yeah....that's something experts should do, particularly considering the costs of those reagents.
