This is a really great resource for people starting out in proteomics research. I'm a graduate student, and I have not yet seen such a well laid out book. The protocols are really well formatted. The importance of steps is explained (to the side, so you can skip over them if you already know), there are hints similar to what you would get if you were training from a real person, and the diagrams are very clear. I keep checking this out at the library (grad student salary), but if I had the money, I would definitely buy this book.
