Preparation and Microinjection of x-Rhodamine-Labeled Vimentin

Edward R. Kuczmarski and Robert D. Goldman

This protocol was adapted from "Imaging Intermediate Filament Proteins in Living Cells," Chapter 30, in Live Cell Imaging (eds. Goldman and Spector). Cold Spring Harbor Laboratory Press, Cold Spring Harbor, NY, USA, 2005.


INTRODUCTION

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.
