Fluorescence energy transfer between Cys-10 residues in F-actin filaments.

Fluorescence energy transfer was measured between Cys-10 residues in an F-actin filament using 5-[2-((iodoacetyl)amino)-ethyl]aminonaphthalene-1-sulphonic acid (1,5-IAEDANS) as a fluorescence energy donor and 4-dimethylaminophenylazophenyl-4'-maleimide (DABMI) as the acceptor. Both labels were covalently attached to Cys-10 residues in an F-actin filament. Taking the helical structure of the F-actin filament into consideration, the radial coordinate of Cys-10 was calculated to be 23 A. This corresponds to a distance between adjacent sites along the long pitch helix of 56.1 A and along the genetic helix of 53.3 A.

Monoclonal antibodies directed against skeletal muscle actin.

The development of a monoclonal antibody directed against rabbit skeletal muscle monomeric actin is described. The production of the monoclonal antibody followed a standard hybridoma technique, the antibody being purified by affinity chromatography. It was found to be of the IgM class. Antibody specificity for rabbit skeletal actin was demonstrated by radioimmunoassay. The antibody failed to bind to actin in Western Blot experiments, presumably due to modification of the antigenic determinant on actin during the Western Blot procedure. The antibody was also shown to bind to two other isotypes of actin, i.e. actin from squid mantle muscle and bovine myocardium.
