Extraction of detergents from hydrophobic proteins with isopentanol: application to electrophoretic analysis of photosynthetic bacterial hydrophobic proteins
Abstract
The method for extracting Triton X-100 used by I. H. Mather and C. B. Tampling [Anal. Biochem. 93, 139-142 (1979)], has been extended to other detergents of different charge and chemical nature. All the detergents tested can be extracted with isopentanol in conditions in which not more than 8% of hydrophobic or hydrophilic protein is lost from the water phase. The removal of detergent from reaction centers and light harvesting protein-pigment complexes of photosynthetic bacteria, eliminates the artifacts of oligomers when analyzed by sodium dodecyl sulfate-gel electrophoresis.
