Quantitative analysis of proteins in detergent-resistant membrane fractions analyzed by mass spectrometry. (A) Proteins in DRM (TI) fractions generated using the conventional or modified methods were analyzed by tandem mass spectrometry and classified as either nuclear, non-nuclear or unannotated based on Gene Ontology cellular component terms. The pie-charts demonstrate the marked reduction in proteins identified as 'nuclear' with the modified extraction procedure. (B) Venn diagrams illustrating the distinct and overlapping protein compositions of TI fractions isolated by each method.
