No, sometimes slow refolding is best. This can occur if folding
intermediates are populated in any case, and they are solubilized by the
presence of denaturant, whereas they aggregate without it.
Of course, fast dilution out of denaturant into buffer containing other
additives might still be a better choice.

wie und wo sieht man in den KernÖl-Sossen nach?
