Exceptions are e.g. proteins that were previously stabilised by covalent cross-linking and the SDS-resistant protein complexes, which are stable even in the presence of SDS (the latter, however, only at room temperature).
Son excepcións, por exemplo, as proteínas que foron previamente estabilizadas por enlaces cruzados covalentes e os complexos proteicos resistentes ao SDS, que son estables mesmo en presenza de SDS (isto último só a temperatura dunha habitación).
