To examine the activities and identity of enzymes associated with organelles such as microsomes and mitochondria, proteins from mouse liver were extracted using the non-ionic detergents Nonidet P-40 (NP-40), polyoxyethylene sorbitan monooleate (Tween 80), polyoxyethylene isooctylphenyl ester (Triton X), n-octyl beta-D-glucoside (octyl glycoside) or anionic detergent sodium dodecylsulfate (SDS) after the removal of cytosolic proteins. The proteins extracted by detergents were separated by non-denaturing two-dimensional electrophoresis (2-DE). The activities of esterase and aldehyde dehydrogenase were retained by non-denaturing 2-DE after treatment with each non-ionic detergent, but the activities were reduced or lost when the proteins were extracted with more than 0.5% SDS. For proteomic analysis of the organelle-associated proteins in mouse liver, proteins were separated by non-denaturing 2-DE and were identified using electrospray ionization tandem mass spectrometry (ESI-MS/MS) after the proteins were solubilized by octyl glycoside, NP-40 and 0.1% SDS. Several organelle-associated proteins such as carboxylesterase, aldehyde dehydrogenase, glucose regulated protein and HSP60 were identified. These results indicate that the activities and identity of detergent-soluble enzymes can be examined by this non-denaturing 2-DE and mass spectrometry.
