An advanced textbook/resources for experimental techniques?

[Dorothea]

My background is in computer science, but I'm now in this biology PhD program. I've got plenty of biology textbooks, but this course I'm taking is focusing on experimental techniques and I'm really lost. Is there an online resource or recent textbook that focuses on the current biology experimental techniques? Obviously, stuff on blots, but the more advanced stuff too on using fluorescence and radioactive labeling, site-directed mutagenesis, etc. In the exams we constantly have to design experiments and describe the "controls." I'm only just learning what controls ARE! What resources are out there to help me?
