Million-fold sensitivity enhancement in proteopathic seed amplification assays for biospecimens by Hofmeister ion comparisons.

abstract：:Protein ubiquitination plays an important role in ATP-dependent protein turnover, and it also may regulate other cellular events. Covalent attachment of ubiquitin to other proteins is catalyzed by three different enzymes, E1, E2, and E3. We have previously shown that protein ubiquitination can be regulated by phosphor...
