So...this might not seem like such a big deal...unless you're about to get 1,000 samples delivered for TMT quantification....
PD 2.x can do the quantification (you just need to build a quan method that has this additional channel)
More information Dr. Saba was able to hunt down:
Oh. If you don't want to do the work and just want to add TMT11plex to your copy of PD 2.1 (haven't checked to see if it works in PD 2.0), I exported a quantification method and you can download it from my DropBox here. (I think you can ignore signing in if you don't have a DropBox account and it will still, grumpily, allow you to download the method.
If you go to -->Administration --> Maintain Quantification methods you can import the method there. TAADAA!! 10% more samples quantified and around 0% more work!
EDIT (12/11/16): I can't seem to figure out where to buy the 131C reagent. Hold up, this might not be 100% out yet! Will update when I know more!
