Electron Microscopy of the Cytoskeleton of Cultured Cells - http://www.borisylab.northwestern.edu/pages/protocols/electmicrosc.html

Category: Microscopy Protocols: Electron Microscopy Protocols

Article describe the preparation of cells for correlative electron microscopy after live light microscopic observation of fluorescently labeled cytoskeletal proteins microinjected into the same cells. Since identification of cytoskeletal elements in electron microscopic preparations is an essential part of any correlative study, procedures for immunogold labeling of cytoskeletal components and for myosin S1 decoration of actin filaments are also described. - [Read Electron Microscopy of the Cytoskeleton of Cultured Cells]

Preparation and Microinjection of x-Rhodamine-Labeled Vimentin Protocol - http://www.cshprotocols.org/cgi/content/abstract/2007/3/pdb.prot4676

Category: Cytoskeleton Protocols: Intermediate Filaments Protocols

Intermediate filaments (IF) are major cytoskeletal systems of vertebrate and many nonvertebrate cells whose expression is cell-type specific and developmentally regulated. This protocol describes the x-rhodamine labeling of one type of IF, vimentin, and a method for microinjection of the labeled vimentin into cultured cells. IF dynamics can then be examined with fluorescence microscopy. - [Read Preparation and Microinjection of x-Rhodamine-Labeled Vimentin Protocol]

Category: Cytoskeleton Protocols: Intermediate Filaments Protocols

Intermediate filaments (IF) are major cytoskeletal systems of vertebrate and many nonvertebrate cells whose expression is cell-type specific and developmentally regulated. This protocol describes a method for purifying one type of IF, vimentin, from bovine lens tissue. Purification of human vimentin expressed in Escherichia coli is also described. These methods are useful in the preparation of other IF protein subunits for microinjection studies as well. - [Read Purification of Bovine Lens and Bacterially Expressed Human Vimentin Protocol]
