A host of fractionation procedures are employed by cell biologists. Each organelle has characteristics (size, shape and density for example) which make it different from other organelles within the same cell.
New methods based on resonance energy transfer (RET) are becoming widespread for the evaluation of protein-protein interactions in living cells. These techniques can also be used to define protein rearrangement, conformation dynamics or the role of ligand and receptor levels, to screen for antagonists, and to study dimerization sites within the cell [1].
