I think one or two questions at max but the difference between 29 and 25 is one question. 🙂 Don't skip anything. If you have any specific questions please don't hesitate to send me a PM. I'll try to get back to you ASAP. (Give me a day or two to empty my box. I'll be out of town for 1-2 days)
Kaplan is pretty comprehensive. I remember a chapter in their book that covered this kind of stuff. Don't spend too much time on this procedure stuff though. Just a surface idea. You arn't trying to be a protein chemist.
