Epoxide hydrolase is a marker for the smooth endoplasmic reticulum in rat liver. 1985

M M Galteau, and B Antoine, and H Reggio

Epoxide hydrolase (EH, EC 3.3.2.3) was chosen as a potential marker for smooth endoplasmic reticulum, because this enzyme is inducible by drugs such as phenobarbital. The hypothesis was verified in rat liver using immunochemical and immunocytochemical techniques. Antibodies were raised to the purified protein. These antibodies were affinity purified using the enzyme immobilized on Sepharose Ultrogel. The specificity of the antibodies was assayed by immunoelectrotransfer (Western blot). The labelling of rat liver thin frozen sections with protein A-gold particles demonstrated that the antibodies specifically recognised smooth endoplasmic reticulum membranes. Rough endoplasmic reticulum, other intracellular organelles and plasma membrane were unlabelled.

D007118	Immunoassay	A technique using antibodies for identifying or quantifying a substance. Usually the substance being studied serves as antigen both in antibody production and in measurement of antibody by the test substance.

D008099	Liver	A large lobed glandular organ in the abdomen of vertebrates that is responsible for detoxification, metabolism, synthesis and storage of various substances.	Livers
D008297	Male		Males
D008854	Microscopy, Electron	Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen.	Electron Microscopy

D011919	Rats, Inbred Strains	Genetically identical individuals developed from brother and sister matings which have been carried out for twenty or more generations or by parent x offspring matings carried out with certain restrictions. This also includes animals with a long history of closed colony breeding.

D002499	Centrifugation, Density Gradient	Separation of particles according to density by employing a gradient of varying densities. At equilibrium each particle settles in the gradient at a point equal to its density.

D004721	Endoplasmic Reticulum	A system of cisternae in the CYTOPLASM of many cells. In places the endoplasmic reticulum is continuous with the plasma membrane (CELL MEMBRANE) or outer membrane of the nuclear envelope. If the outer surfaces of the endoplasmic reticulum membranes are coated with ribosomes, the endoplasmic reticulum is said to be rough-surfaced (ENDOPLASMIC RETICULUM, ROUGH); otherwise it is said to be smooth-surfaced (ENDOPLASMIC RETICULUM, SMOOTH).
