Ribosome in the lead

Ribosome is not a multiprotein complex, and not an enzyme. Ribosome is an RNA-protein complex (scaffold is mainly rRNA) and due to the catalytic site position, ribosome is a ribozyme. Should this article be moved to "biomolecular complex"? Because then one could include any stable complex determined by computational or structural means and may include DNA (nucleosome=DNA + protein), RNA (ribosome, spliceosome, telomerase,...= RNA + protein), protein, lipid (transmembrane protein complexes usually have some essential lipids bound), sugars (glycosylation of various proteins in complexes),...

List of papers about stoichiometry determination

An article Protein stoichiometry has been proposed for deletion. The text makes no sense, but I thought that the attached list of measurement methods may contain useful sources, so rescued it here as a backup.

Absolute Quantification (AQUA)^[1]
Multiple Reaction Monitoring (MRM)^[1]
Fluorescence microscopy^[2]
Step-wise photobleaching of dye-labelled subunits (photobleaching)^[3]
hydrophobic photolabeling (HyPLa)^[4]
peptide-based mass spectrometry^[5]
proteomics-based mass spectrometry^[6]
cell fusion and single molecule imaging^[7]
isotope-coded mass spectrometry^[8]
