Indirect immunofluorescence staining of cultured neural cells.

Immunofluorescence is a technique allowing the visualization of a specific protein or antigen in cells or tissue sections by binding a specific antibody chemically conjugated with a fluorescent dye such as fluorescein isothiocyanate. There are two major types of immunofluorescence staining methods: (1) direct immunofluorescence staining in which the primary antibody is labeled with fluorescence dye and (2) indirect immunofluorescence staining in which a secondary antibody labeled with fluorochrome is used to recognize a primary antibody. This chapter describes procedures for the application of indirect immunofluorescence staining to neural cells in culture.
