Surely, if you have the specific mRNA for the protein that you want to
label you could simply do in vitro translation (using 35S-met), purify
the protein of your interest and use it as the probe. However, labeling
the pure protein with 125I may be a better and easier alternative.
Iodination protocols can be had from any protein protocol book or from
the Meth. Enzymol. volumes. Protein-protein crosslinking is achieved by
uv-irradiation, and this needs to be standardized for each system and the
protein pairs.
