Evaluation of techniques for immunofluorescent staining of microtubules in cultured plant cells
DH Simmonds, RW Seagull and G Setterfield
Various modifications to the immunofluorescent labeling procedures for microtubules in plant cells have been compared using cell cultures of Vicia hajastana Grossh. Using serial section electron microscopic reconstructions as a reference, we have chosen as our standard procedure a method that maximizes both the preservation of the cytoskeleton and the proportion of cells staining, while minimizing the degree of nonspecific staining. The critical steps of the procedure include stabilization of the cytoskeleton, cell wall permeabilization, and cell extraction. To maintain structural integrity during the procedure, it is necessary to stabilize the cytoskeleton with paraformaldehyde. To facilitate antibody penetration into the cell, it was necessary that the walls be made permeable via partial enzymatic digestion. Detergent extraction of cells increased the proportion of cells staining and decreased the level of nonspecific binding of the antibodies. The procedures detailed in this article provide a good starting point for the application of immunofluorescent labeling techniques to other plant systems.
