good discussion, Thanks a lot!!
Here is my point of view, proteomics per se is just a method, that's it, and to be honest, it is not that mature at all, so that's why proteomics itself becomes a hot area for research. Biological validation of your proteomics data like RT-PCR, western, or even genomics surely is important for the discovery of the underlying biological mechanism, but don't forget proteomics is not just 2DE/2DLC coupled with MS identification, it can go much far beyond that. Proteomics for PTM, interactomics, proteomics target on specific organelle or protein complex, membrane proteomics, even topology for single protein, they all add more information for unveiling the biological mechanisms.....so my point is, if you want to do something 'deep' base on proteomics, you can
1 use conventional methods to validate your hypotheses derived from you proteomics data or
2 use new or more 'targeted' proteomics techniques to investigate the proteome further
3, if you are an engineer, develop a new proteomics workflow for a specific type of biological question/sample
