Immunoelectronmicroscopic localization of alpha-actinin in skeletal muscle cells. 1977

B P Lane, and J Elias, and E Drummond

The ultrastructural distribution of alpha-actinin in skeletal myocytes was studied by a sensitive method that permits localization of antigenic proteins in intact fixed cells rather than in glycerol estracted tissues or isolated cell fractions. Binding to the Z line of specific antiserum produced in rabbits immunized with highly purified alpha-actinin was demonstrated by deposition at this site of a reaction product of horseradish peroxidase that had been coupled to antigen-binding fragments of sheep anti-rabbit gamma globulin.

UI MeSH Term Description Entries
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
D009124 Muscle Proteins The protein constituents of muscle, the major ones being ACTINS and MYOSINS. More than a dozen accessory proteins exist including TROPONIN; TROPOMYOSIN; and DYSTROPHIN. Muscle Protein,Protein, Muscle,Proteins, Muscle
D009132 Muscles Contractile tissue that produces movement in animals. Muscle Tissue,Muscle,Muscle Tissues,Tissue, Muscle,Tissues, Muscle
D000185 Actinin A protein factor that regulates the length of R-actin. It is chemically similar, but immunochemically distinguishable from actin. alpha-Actinin,Eu-Actinin,beta-Actinin,Eu Actinin,alpha Actinin,beta Actinin
