Assays for membrane and intracellular signalling events

The aims of this book are to provide workers in the field of angiogenesis with a critical analysis of the various methods used to study angiogenesis. As such, I would suggest that this chapter should present less specific data on caveolae etc and instead place a greater emphasis on the actual techniques used to study the signalling pathways, including a discussion of their strengths and weaknesses. Please can you also add a few more of the commonly used methods that look at how signals cross the membrane, measuring protein phosphorylation, microarrays, RT-PCR etc.
