Do you just want to sequence one protein?
Do you really want to avoid those weirdos at a mass spec core?
Do you prefer instruments you can carry around if you want?
Well do I ever have a solution for you! The Quantum SI Palladium is finally out! They hired a friend of mine a long time ago and it was all secret what she was doing.
You get a PCR sized thing and you never go to that mass spec core again as long as you only want to do one protein at a time. This thing sequences your one protein on your benchtop #1 or number 3 or at lunch at a restaurant with you. You buy these reagent kits and while it is error prone, you give it so much protein that it eventually gets it right!
DISCLAIMERS OVER THERE! I literally don't know how this thing works.
