Hi Laurent,

Your question reminded me of this impressive piece of work that did the same thing in yeast:

Wu, J.Q. and T.D. Pollard, Counting cytokinesis proteins globally and locally in fission yeast. Science, 2005. 310(5746): p. 310-314.

Wu, J.Q., C.D. McCormick, and T.D. Pollard, Counting proteins in living cells by quantitative fluorescence microscopy with internal standards, in Biophysical tools for biologists, vol 2: In vivo techniques. 2008, Elsevier Academic Press Inc: San Diego. p. 253-+.

Might be of interest to you as well.
