Whole-mount confocal immunofluorescence of mammalian CNS.
Brain Research. Brain Research Protocols
Bright-field wholemount labeling techniques applied to the mammalian central nervous system (CNS) offer advantages over conventional methods based on sections since an immediate and three-dimensional view of the stained components is provided. It thereby becomes possible to survey and count large number of cells and fibers in their natural relationships. The ability of confocal laser scanning microscopy to visualize in one focal plane the fluorescence associated with multiple markers could be most valuable by the availability of reliable wholemount fluorescent techniques. Accordingly, based in our previously published bright-field wholemount protocols [Brain Res. Prot. 2 (1998) 165-173], we have devised an effective immmunofluorescence wholemount procedure. We show that reliable wholemount fluorescent staining can be obtained using isolated complete CNS aged up to rat embryonic day 17, with antibodies penetration in the millimeter range. Examples are shown of preparations in which colocalization can be observed in nerve cells of cytoskeletal and calcium-binding proteins.
