Detergent - an overview | ScienceDirect Topics- detergents lab biology journal ,Burcu Devrim, Asuman Bozkır, in Nanostructures for Antimicrobial Therapy, 2017. 2.1.1.4 Detergent Depletion Method. The detergent depletion method is commonly employed to prepare LUVs. In this method, the detergents are used to solubilize the lipids in micellar solution (Walde et al., 2010).Since the detergent protects the hydrophobic part of lipids from interacting with the aqueous solution ...Detergent - an overview | ScienceDirect TopicsDirk Linke, in Methods in Enzymology, 2009. 6.2 Mass spectrometry and nuclear magnetic resonance (NMR) measurements. Detergents are generally detrimental to mass spectrometry applications, as they themselves can be ionized, leading to strong signals in different detector systems. As a rule of thumb, MALDI-MS is more resistant to detergents than ESI-MS, but in general, detergents need to be ...
