I would like to conduct a simple dimerization experiment for some protein I'm collecting from a cultured cells. My thought is, that if I'm running a non-reducing, denaturing PAGE gel, then removing beta-mercaptoethanol/DTT from the sample buffer should be enough to allow di-sulfide bonds to form.
I have seen several authors incubate the cells first with a drug called BSS that diffuses across membranes and creates protein cross-links. I may be wrong, but the use of this drug seems more appropriate when trying to follow up with an immunoprecipitation or a pull-down assay.
If anyone has any experience with this, could you please enlighten me?
